Supercharacter theory offers a tractable refinement of classical character theory by consolidating characters and conjugacy classes into supercharacters and superclasses. Initially conceptualised to ...
Mathematics of Computation, Vol. 55, No. 192 (Oct., 1990), pp. 705-722 (18 pages) We consider the bit-complexity of the problem stated in the title. Exact computations in algebraic number fields are ...
Suppose a finite group acts on a scheme X and a finite-dimensional Lie algebra g. The corresponding equivariant map algebra is the Lie algebra M of equivariant regular maps from X to g. We classify ...
