Word problem (mathematics)

In computational mathematics, a word problem is the problem of deciding whether two given expressions are equivalent with respect to a set of rewriting identities. A prototypical example is the word problem for groups, but there are many other instances as well. Some deep results of computational theory concern the undecidability of this question in many…
