A Note on Lerch’s Formulae for Euler Quotients

چکیده
Lerch’s formulae for Euler quotients in the rings Z and Fq[t] have already been studied. In this paper, we extend the study of these quotients to number fields and the Carlitz module. In the number fields case, we prove a version of Lerch’s formula for OKHil , the ring of integers of the Hilbert class field of a number field K. In the Fq[t] case, we replace the usual multiplication in Fq[t] with the Carlitz module action ⇢ and prove two new versions of this formula. In addition, we relate these congruences to Carlitz Wieferich primes in Fq[t]. All our proofs use properties of Carlitz polynomials.

Lerch’s Theorems over Function Fields
In this work, we state and prove Lerch’s theorems for Fermat and Euler quotients over function fields defined analogously to the number fields. 1. Results The Fermat’s little theorem states that if p is a prime and a is an integer not divisible by p, then ap−1 ≡ 1 mod p. This gives rise to the definition of the Fermat quotient of p with base a, q(a, p) = ap−1 − 1 p , which is an integer. This q...
متن کاملDouble Integrals and Infinite Products for Some Classical Constants via Analytic Continuations of Lerch’s Transcendent
The two-fold aim of the paper is to unify and generalize on the one hand the double integrals of Beukers for ζ(2) and ζ(3), and those of the second author for Euler’s constant γ and its alternating analog ln(4/π), and on the other hand the infinite products of the first author for e, and of the second author for π and e . We obtain new double integral and infinite product representations of man...

متن کاملNote on Dedekind Type Dc Sums
In this paper we study the Euler polynomials and functions and derive some interesting formulae related to the Euler polynomials and functions. From those formulae we consider Dedekind type DC(Daehee-Changhee)sums and prove reciprocity laws related to DC sums.
متن کاملHurwitz ball quotients
We consider the analogue of Hurwitz curves, smooth projective curves C of genus g ≥ 2 that realize equality in the Hurwitz bound |Aut(C)| ≤ 84(g − 1), to smooth compact quotients S of the unit ball in C. When S is arithmetic, we show that |Aut(S)| ≤ 288e(S), where e(S) is the (topological) Euler characteristic, and in the case of equality show that S is a regular cover of a particular Deligne–M...
