An L2-quotient algorithm for finitely presented groups on arbitrarily many generators
چکیده انگلیسی

We generalize the Plesken-Fabiańska L2-quotient algorithm for finitely presented groups on two or three generators to allow an arbitrary number of generators. The main difficulty lies in a constructive description of the invariant ring of GL(2,K) on m copies of SL(2,K) by simultaneous conjugation. By giving this description, we generalize and simplify some of the known results in invariant theory. An implementation of the algorithm is available in the computer algebra system Magma.
