摘要
We obtain a series of new results on the problem of irreducibility of commuting varieties associated with symmetric pairs or, in other words, -graded simple Lie algebras. In particular, we present many examples of reducible commuting varieties and show that the number of irreducible components can be arbitrarily large.
