M(atrix) Theory on an Orbifold and Twisted Membrane M(atrix) Theory on an Orbifold and Twisted Membrane 1
M(atrix) theory on an orbifold and classical two-branes therein are studied with particular emphasis to heterotic M(atrix) theory on S1=Z2 relevant to strongly coupled heterotic and dual Type IA string theories. By analyzing orbifold condition on Chan-Paton factors, we show that three choice of gauge group are possible for heterotic M(atrix) theory: SO(2N), SO(2N + 1) or USp(2N). By examining a...

M(atrix) theory on an orbifold and classical two-branes therein are studied with particular emphasis to heterotic M(atrix) theory on S1/Z2 relevant to strongly coupled heterotic and dual Type IA string theories. By analyzing orbifold condition on Chan-Paton factors, we show that three choices of gauge group are possible for heterotic M(atrix) theory: SO(2N), SO(2N + 1) or USp(2N). By examining ...
متن کاملOrbifold and Twisted Zero-branes
M(atrix) theory compactified on an orbifold T9/Z2 is studied. Via zero-brane parton scattering we find that each of the 2 = 254 orbifold fixed points carry −1/32 units of zero-brane charge. The anomalous flux is cancelled by introducing a twisted sector consisting of 32 zero-branes that are spacetime supersymmetry singlets. These twisted sector zero-branes are nothing but gravitational waves pr...
متن کاملModuli of Twisted Orbifold Sheaves
We study stacks of slope-semistable twisted sheaves on orbisurfaces with projective coarse spaces and prove that in certain cases they have many of the asymptotic properties enjoyed by the moduli of slope-semistable sheaves on smooth projective surfaces.
متن کاملTwisted Jet, Motivic Measure and Orbifold Cohomology
We introduce the notion of twisted jet. For a DeligneMumford stack X of finite type over an algebraically closed field k, a twisted ∞-jet on X is a representable morphism D → X such that D is a smooth Deligne-Mumford stack with the coarse moduli space Spec k[[t]]. We study the motivic measure on the space of the twisted ∞-jets on a smooth Deligne-Mumford stack. As an application, we prove that ...
