摘要In a previous paper [Jian-Huang She, J. High Energy Phys. 01 (2006) 002.] using a matrix model, we showed that closed string tachyons can resolve spacelike singularity in one particular class of Misner space (with antiperiodic boundary conditions for fermions around the spatial circle). In this note, we show that for Misner space without closed string tachyons, there also exists a mechanism to resolve the singularity in the context of the matrix model, namely, cosmological winding string production. We show that here space and time also become noncommutative due to these winding strings. Employing the optical theorem, we study the bulk boundary coupling by calculating the four-open-string cylinder amplitudes.
