Extending a result of Rabin, It Is shown that the word problem for hnear groups (groups of matrices) over a field of characteristic 0 is solvable in (deterministic) logspace As an apphcatlon of this result, it follows that the word problem for free groups and hence the membership problem for the two-sided Dyck language are solvable in logspace KEY WORDS AND "PHRASES. word problems, linear groups, logspace CR CATEGORIES 5 25
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
