欧拉公式(Euler's Formula):即e^{i x}=\cos(x)+i \sin(x),复分析中最基础的公式之一。大家非常熟悉的欧拉恒等式(即所谓数学中最优雅公式之一)的e^{i \pi} + 1 = 0,就是这个公式令x = \pi时的特殊情况。 欧拉-费马定理(Euler-Fermat Theorem):即a^{\phi(n)}\equiv 1(mod\ n),数论中的重...
- n|phi(m), the euler totient function, - (n, phi(m)/n) = 1, - Another one ? Maybe for q = p^d we'd want (n,d) = 1, We can note that if m = r^e with (e-1,n) = 1 or e = 1, then r = a*n + 1 with (a,n) = 1 is a suitable form for m as then p...
Euler Phi Function Calculator n = In number theory, the Euler Phi Function or Euler Totient Function φ(n) gives the number of positive integers less than n that are relatively prime to n, i.e., numbers that do not share any common factors with n. For example, φ(12) = 4, since ...
Asymptotic formulas of the Euler-Maclaurin type are proved for the sum $$\\\frac{1}{n}\\\sum\\\limits_{k = 1}^{n - 1} {\\\Phi \\\left( {frac{k}{n}} ight) as n o \\\infty .} $$ Here Φ(χ) is a sufficiently smooth function on the interval (0,1) and has singula...
The formula for the number of necklaces of content `alpha` a composition of `n` is: .. MATH:: sum_{d|gcd(alpha)} phi(d) inom{n/d}{alpha_1/d, ldots, alpha_ell/d}, where `phi(d)` is the Euler `phi` function. EXAMPLES:: sage: Necklaces([]).cardinality() 0 sage: ...

5.1 Vector fields and the phase We discuss here some aspects related to the interaction of the vector fields V\in \{S,\Omega \} and the phase functions \Phi _{\mu \nu } as in (2.9). We use subscripts to denote the Fourier variable in which a vector field acts, so that ...
