El tamaño máximo de entre $\varphi(n)$ dividido por $\lambda(n)$.

Question

Quiero encontrar a $$f(n) = \max\left\{\frac{\varphi(k)}{\lambda(k)} : 1 \leq k \leq n\right\}$$

En otras palabras, quiero encontrar el valor máximo de $\frac{\varphi(k)}{\lambda(k)}$ al $k$ es restringido.

$\lambda(n)$ es el Carmichael función, el más pequeño de $k$ tal que para todos los $a$ tal que $\gcd(a,n)=1$ la siguiente congruencia tiene: $a^{k} \equiv 1 \mod n$. $\varphi(n)$ es el de Euler-phi función. Tenga en cuenta que $\lambda(n) \mid \varphi(n)$.

Ya no espero a $f(n)$ tener una buena expresión en términos de primaria y el número teórico de funciones, empecé a buscar un poco de los límites inferiores. Me encontré con que $$\frac{\varphi(2^k \cdot p_{k+1}\#)}{\lambda(2^k \cdot p_{k+1}\#)} \geq 2^k$$

Aquí $k\#$ es el primorial de la función.

Por lo tanto, sé que la fracción es ilimitado, y que $$f(n) \in \Omega(n^{1/ \ln \ln n})$$

Sin embargo $n^{1/ \ln \ln n}$ todavía está acotada arriba por todas las funciones de energía con una potencia positiva. ¿Alguien tiene una asintóticamente mejor de ruedas o una prueba de que este es el mejor bound?

Miré a OEIS, que tiene esta secuencia A034380. He encontrado que los más pequeños de $n$ tal que $f(n)\geq 108$$n=3591$, el más pequeño de $n$ tal que $f(n)\geq 128$$n=5440$. Sin embargo, mi método da $1241560320$ como un número que es mayor que 128. Claramente, hay un cierto margen para la mejora.

Conjetura: Se Jagy se encontró una fuerte evidencia numérica que $f(n)$ eventualmente supera el $n^{1-\varepsilon}$ por cada $\varepsilon > 0$. Una prueba (o refutación) de esto sería muy bienvenida.

Answer 1

Esta vez dejé que el destino número de Carmichael ser el mínimo común múltiplo de los números de $1$ $w.$Esto es más eficiente en términos de número de divisores. El Superior Altamente Compuesto de Números y la Colosalmente Números Abundantes compartir la propiedad principal de este LCM, que es el exponente de algunos de los mejores $p$ es proporcional a $1/ \log p.$ Como resultado de ello, la multiplicación de la contribución de cada uno de los prime es (muy) aproximadamente igual, porque $$x^{1/ \log x} = e.$$

We know from Legendre's theorem on the exponent of a prime dividing a factorial that the exponent here of $p$ is proportional to $1/p.$ So the smaller primes give a large multiplicative part, as $x^{1/x}$ goes to $1$ as $x \rightarrow \infty.$ Not an astonishing difference, I guess.

The program got incredibly slow doing the lcm of the numbers up to $23,$ so I will just paste in the lcm's up to $19.$

Got a much abbreviated output, so the whole thing goes much faster and I am able to compare things. It turns out the first time $\registro de f(n) / \log n$ passes 0.999 is actually when the assigned Carmichael number is the LCM up to $31,$ and the first time we pass 0.9999 is when the assigned Carmichael number is the LCM up to $43.$ I had it put in logs base 10 as well.

As far as proving anything, let me describe the construction this way: for a number $L$ we let $C = \operatorname{lcm} (1,2,3,\ldots,L).$ We find all positive divisors $d | C.$ For each such $d,$ we check $q = 1 + d.$ If $q$ is prime, then $p$ becomes a factor of $n.$ Now if, in addition, $q \leq L,$ then $q$ gets an exponent larger than $1,$ because we get $q | C$ this way. In fact, we give $p$ the largest possible exponent such that the Carmichael number of $p^$ divides $C.$ If, instead, $q > L$ then the exponent of $q$ is precisely $1.$

This means that the number of primes that arise as $q=1+d$ with $d | L$ is a big part of the giant size of $n.$ It is easy to predict the number of positive divisors of $C$ because we know how it factors. Add one to each, many become prime, many do not. I made a table, it suggests that the number of primes is faster than polynomial as a function of $L$ but slower than exponential.

Let's see. In the table above, the value of $L$ is on the left, let $P$ be the count of primes constructed. The final number, called "log ratio," is just $\log P / \log L.$ This seems to keep growing, so $P$ seems to be growing faster than a polynomial in $L.$

Next I repeated the table, but this time the "log ratio" is $\log P / L,$ which seems to be decreasing to $0,$ so it seems $P$ is growing slower than an exponential in $L$

There are infinitely many growth rates between polynomial and exponential as a function of $L;$ uno de los más fáciles de tipo $$e^{\sqrt L}$$

Answer 2

Tengo una referencia en MO; ver http://mathoverflow.net/questions/210144/number-of-primes-one-larger-than-divisors-of-a-fixed-number-which-is-lcm-of-1-2#comment520981_210144 y

http://www.math.drexel.edu/~eschmutz/PAPERS/lambda.pdf

En el Teorema $1$ en la primera página de la Erdos-Pomerance-Schmutz artículo, anuncian la existencia de una constante $c$ y una secuencia de números de $n$ ir $\infty,$ tal que $$\lambda(n) < \left( \log n \right)^{c \log \log \log n}.$$

Por otro lado, para todos los $n \geq 3,$ encontramos en Rosser y Schoenfeld (1962) que $$\varphi(n) > \frac{n}{ e^\gamma \log \log n + \frac{3}{\log \log n}}.$$

Así, en la secuencia especial de Erdos-Pomerance-Schmutz, nos encontramos con $$\frac{ \varphi(n)}{\lambda(n)} > \frac{n}{ \left( e^\gamma \log \log n + \frac{3}{\log \log n} \right) \left( \left( \log n \right)^{c \log \log \log n} \right) }$$ que finalmente es más grande que cualquier $n^{1-\delta}.$ no estoy del todo claro lo que su secuencia.

Answer 3

Me tomó un tiempo, pero escribí algo en C++ con el GMP para encontrar el máximo posible de la $n$ que tienen un número de Carmichael, además, me tomó de los números de Carmichael ser $w!$$4 \leq w \leq 12,$, lo que lleva a una buena cantidad de tiempo como es. La cantidad de $\log f(n) / \log n$ evidentemente pone arbitrariamente cerca de $1$ de esta forma.

Answer 4

Esto es condicional en Dickson de la conjetura, pero pueden ser de su interés.

Usted puede elegir cualquier admisible el primer k-tupla $(b_1=0,b_2,b_3,\ldots,b_k)$. Por definición, el $b_i$ evitar algunos de residuos modulo cada primer, y por lo tanto para hacer $\{(2+b_i)n+1\}$. Entonces es una consecuencia de Dickson conjetura de que $q_i=(2+b_i)n+1$ son simultáneamente principal para $1\le i \le k$ para infinidad de opciones de $n$.

Escribir $N=\prod q_i$, luego $$\begin{align} N &= \prod_{i=1}^k\left((2+b_i)n+1\right) \\ & < (n+1)^k\prod_{i=1}^k (2+b_i) \\ &= C_1 (n+1)^k \end{align}$$ y $$\begin{align} \varphi(N)&=\prod_{i=1}^k (q_i-1) \\ &= n^k \prod_{i=1}^k (2+b_i) \\ &= C_1 n^k \end{align}$$ y $$\begin{align} \lambda(N) &= \operatorname{lcm} \left(2n,(2+b_2)n,\ldots,(2+b_k)n\right) \\ & \le n\operatorname{lcm}\left(2+b_2,2+b_3,\ldots,2+b_k\right) \\ &= C_2 n \end{align}$$ Donde $C_1$ $C_2$ depende de la elección de k-tupla, pero no en $n$. Así $$f(N) = \frac{\varphi(N)}{\lambda(N)} \ge \frac{C_1}{C_2}n^{k-1} = \Theta\left(N^{1-1/k}\right)$$ y mediante la elección apropiada de $k$ puede ser hecho a crecer más rápido de lo $N^{1-\epsilon}$ cualquier $\epsilon>0$.

Por ejemplo, $(0,2,6,12,14,20,24,26,30,32)$ es admisible 10-tupla de primer diferencias. Nos encontramos simultánea de los números primos $q_i$ cuando $$n = 190103265 \\ N \aprox 1.540\times10^{94} \\ \varphi(N) \aprox 1.540\times 10^{94} \\ \lambda(N) = 544544n \aprox 1.035\times10^{14}\\ f(N) \aprox 1.488\times10^{80} \\ \frac{\log f(N)}{\log N} = 0.8512\ldots$$ y cuando $$n = 5092580565 \\ N \aprox 2.93\times10^{108} \\ \varphi(N) \aprox 2.93\times 10^{108} \\ \lambda(N) = 544544n \aprox 2.77\times10^{15}\\ f(N) \aprox 1.057\times10^{93} \\ \frac{\log f(N)}{\log N} = 0.8576\ldots$$

Para mayor $n$ de que el rendimiento de las soluciones que se han $\log_N f \to 9/10$. Del mismo modo, para una mayor selección de $k$ debemos ser capaces de hacer $\log_N f \to 1-1/k$, aunque en la práctica es difícil encontrar ejemplos.

Answer 5

Una cosa que definitivamente quiero hacer es simplemente encontrar la secuencia de enteros para que su cantidad se incrementa, y el factor de aquellos. Esta es la historia entera de un número de problemas de optimización que se remontan a Ramanujan. Esas son todas las funciones multiplicativas. La mala noticia para usted es que el Carmichael no es una función multiplicativa.

Por favor, eche un vistazo a la siguiente tabla. Parece correcto, en comparación con el OEIS listas de totient y Carmichael valores.

Notificación de la medida en que los dos o tres grandes factores primos se $1 \pmod 3.$ Esto encaja muy bien con el mayor factor primo de ser exactamente uno más grande que el Carmichael valor, como el general Carmichael valor no es el producto sobre el primer factor de potencia, es el mínimo común múltiplo.

Bien, después de ver lo bien 36, 60, 72 hacer, decidí darle la vuelta. Para cada número de Carmichael, examinar cada fuente primaria de energía, que puede dividirse $n$ y todavía dividir el número de carmichael. Luego me enteré de la relación $f(n)$ y ordenados por $\log f(n) / \log n$
