New harmonic number identities with applications
We determine the explicit formulas for the sum of products of homogeneous
multiple harmonic sums when
. We apply these identities to the study of two
congruences modulo a power of a prime
Supercongruences for a truncated hypergeometric series
The purpose of this note is to obtain some congruences modulo a power of a
prime involving the truncated hypergeometric series for and . In the last
section, the special case is considered.Comment: Revised versio
Wolstenholme and Morley, Primes and Pseudoprimes
In this note, we prove is a Morley pseudoprime (of order 2) iff
is a Wolstenholme pseudoprime (of order 2) iff is a Wolstenholme prime iff
is a Morley prime. Concerning pseudoprimes of order 1 that are not powers
of primes, only 3 are known of Wolstenholme's type and absolutely none have yet
been identified of Morley's type
A Characterization of Wilson-Lerch Primes
This note presents criteria in terms of Bernoulli numbers for a prime to be simultaneously a Wilson prime and a Lerch prime.http://www.integers-ejcnt.org/q51/q51.Abstract.htm
