Abstract

This article discusses the existence of SymSPACE(logn)-complete formal languages. It is shown that a recent approach of Alvarez and Greenlaw to define symmetric versions of one-way devices doesn't lead to SymSPACE(log n) complete problems when applied to linear context-free or to one-counter languages.
