Binomial identities — combinatorial and algorithmic aspects Original Research Article

The problem of proving a particular binomial identity is taken as an opportunity to discuss various aspects of this field and to discuss various proof techniques in an exemplary way. In particular, the unifying role of the hypergeometric nature of binomial identities is underlined. This aspect is also basic for combinatorial models and techniques, developed during the last decade, and for the recent algorithmic proof procedures. “Much of mathematics comes from looking at very simple examples from a more general perspective. Hypergeometric functions are a good example of this.
