"Computation of standard bases of ideals of free noncommutative algebras" A.A.Mikhalev* and A.A.Zolotykh Moscow State University, Russia, aamikh@cnit.math.msu.su zolotykh@lsili.ru Abstract: We consider standard bases of free Lie algebras and free associative algebras over rings. The main result is a criterion for a subset of a free algebra to be a standard basis of the ideal it generates. Based on this result we present algorithms to construct standard bases and discuss the termination condition for these algorithms.
