Computing the inverses, their power sums, and extrema for Euler's totient and other multiplicative functions

چکیده
Wepropose a generic dynamic programming algorithm for computing the inverses of a multiplicative function. We illustrate our algorithm with Euler’s totient function and the sum of k-th powers of divisors. Our approach can be further adapted for computing certain functions of the inverses, such as their quantity, the smallest/largest inverse, which may be computed faster than the inverses themselves.

Combinatorial Aspects of the Generalized Euler's Totient
A generalized Euler's totient is defined as a Dirichlet convolution of a power function and a product of the Souriau-Hsu-M ¨ obius function with a completely multiplicative function. Two combinatorial aspects of the generalized Euler's totient, namely, its connections to other totients and its relations with counting formulae, are investigated.
متن کاملAlternating Sums Concerning Multiplicative Arithmetic Functions
We deduce asymptotic formulas for the alternating sums ∑ n≤x(−1)f(n) and ∑ n≤x(−1) 1 f(n) , where f is one of the following classical multiplicative arithmetic functions: Euler’s totient function, the Dedekind function, the sum-of-divisors function, the divisor function, the gcd-sum function. We also consider analogs of these functions, which are associated to unitary and exponential divisors, ...
متن کاملPerturbation bounds for $g$-inverses with respect to the unitarily invariant norm
Let complex matrices $A$ and $B$ have the same sizes. Using the singular value decomposition, we characterize the $g$-inverse $B^{(1)}$ of $B$ such that the distance between a given $g$-inverse of $A$ and the set of all $g$-inverses of the matrix $B$ reaches minimum under the unitarily invariant norm. With this result, we derive additive and multiplicative perturbation bounds of the nearest per...
متن کاملMULTIPLICATIVE RELATIONS BETWEEN COEFFICIENTS OF LOGARITHMIC DERIVATIVES OF Fq-LINEAR FUNCTIONS AND APPLICATIONS
We prove some interesting multiplicative relations which hold between the coefficients of the logarithmic derivatives obtained in a few simple ways from Fq-linear formal power series. Since the logarithmic derivatives connect power sums to elementary symmetric functions via the Newton identities, we establish, as applications, new identities between important quantities of function field arithm...
متن کاملIncomplete Kloosterman Sums and Multiplicative Inverses in Short Intervals
We investigate the solubility of the congruence xy ≡ 1 (mod p), where p is a prime and x, y are restricted to lie in suitable short intervals. Our work relies on a mean value theorem for incomplete Kloosterman sums.
