In the last decades, there has been an increasing interest in the classification of isomorphism classes of group gradings on a given algebra. We discuss some difficulties concerning the study of group gradings on infinite-dimensional algebras. Then, we present our results on the classification of the gradings on the infinite-dimensional triangular algebra.
This is joint work with Waldeck Schutzer (UFSCar).
