Convolution identities involving the central binomial coefficients and Catalan numbers [PDF]

open access: yesTransactions on Combinatorics, 2021
We generalize some convolution identities due to Witula and Qi et al‎. ‎involving the central binomial coefficients and Catalan numbers‎. ‎Our formula allows us to establish many new identities involving these important quantities‎, ‎and recovers some known identities in the literature‎.

A q-analog of Ljunggren's binomial congruence [PDF]

open access: yes, 2011
We prove a $q$-analog of a classical binomial congruence due to Ljunggren which states that \[ \binom{a p}{b p} \equiv \binom{a}{b} \] modulo $p^3$ for primes $p\ge5$.
