Randomized trial computes equivariant classes in GL(2) representations, indicating applications for orbit closures.
We compute equivariant fundamental classes of orbit closures in arbitrary GL(2) GL ( 2 ) -representations. As applications, we find degrees of the orbit closures corresponding to elliptic fibrations and self-maps of the projective line.
