Talk: A q-analog of Ljunggren's binomial congruence (Illinois)

A q-analog of Ljunggren's binomial congruence (Illinois)

Date: 2012/10/13
Occasion: Midwest Number Theory Conference for Graduate Students and Recent PhDs IX
Place: University of Illinois at Urbana-Champaign

Abstract

Ljunggren's congruence states that \(\binom{ap}{bp}\) is congruent to \(\binom{a}{b}\) modulo \(p^3\). The goal of this talk is to extend this congruence into the q-world. To this end, the q-binomial coefficients are reviewed and characterized in a variety of ways.
