On some conjectural congruences (1904.02550v1)
Published 4 Apr 2019 in math.NT and math.CO
Abstract: In this paper, we confirm some congruences conjectured by V.J.W. Guo and M.J. Schlosser recently. For example, we show that for primes $p>3$, $$ \sum_{k=0}{p-1}(2pk-2k-1)\frac{\left(\frac{-1}{p-1}\right)_k{2p-2}}{(k!){2p-2}}\equiv0\pmod{p5}. $$
