On the semi-relative condition for closed (topological) strings
We provide a simple lagrangian interpretation of the meaning of the $b_0~-$ semi-relative condition in closed string theory. Namely, we show how the semi-relative condition is equivalent to the requirement that physical operators be cohomology classes of the BRS operators acting on the space of loca...
