we analyze non-relativistic string in newton-cartan background that was found recently in arxiv:1705.03535. we find its hamiltonian formulation and study structure of constraints. we also discuss a relation between string in newton-cartan background and t-duality along null reduction. | remark about non-relativistic string in newton-cartan background and null reduction |
we study the effect of zz instantons in c = 1 string theory, and demonstrate that they give rise to non-perturbative corrections to scattering amplitudes that do not saturate unitarity within the closed string sector. beyond the leading non-perturbative order, logarithmic divergences are canceled between worldsheet dia... | zz instantons and the non-perturbative dual of c = 1 string theory |
