Integral invariants in flat superspace
Michael Movshev, Albert Schwarz, Renjun Xu
We are solving for the case of flat superspace some homological problems that were formulated by Berkovits and Howe. (Our considerations can be applied also to the case of supertor…
Weierstrass cycles and tautological rings in various moduli spaces of algebraic curves
Jia-Ming Liou, Albert Schwarz, Renjun Xu
We analyze Weierstrass cycles and tautological rings in moduli space of smooth algebraic curves and in moduli spaces of integral algebraic curves with embedded disks with special a…
Cohomology ring of the BRST operator associated to the sum of two pure spinors
Andrei Mikhailov, Albert Schwarz, Renjun Xu
In the study of the Type II superstring, it is useful to consider the BRST complex associated to the sum of two pure spinors. The cohomology of this complex is an infinite-dimensio…
BRST cohomology of the sum of two pure spinors
Andrei Mikhailov, Renjun Xu
We study the zero mode cohomology of the sum of two pure spinors. The knowledge of this cohomology allows us to better understand the structure of the massless vertex operator of t…
Homology of Lie algebra of supersymmetries and of super Poincare Lie algebra
M. V. Movshev, A. Schwarz, Renjun Xu
We study the homology and cohomology groups of super Lie algebra of supersymmetries and of super Poincare Lie algebra in various dimensions. We give complete answers for (non-exten…
Homology of Lie algebra of supersymmetries
Michael Movshev, Albert Schwarz, Renjun Xu
We study the homology and cohomology groups of super Lie algebra of supersymmetries and of super Poincare algebra. We discuss in detail the calculation in dimensions D=10 and D=6.…
Alternative Mathematical Technique to Determine LS Spectral Terms
Renjun Xu, Zhenwen Dai
We presented an alternative computational method for determining the permitted LS spectral terms arising from electronic configurations. This method makes the direct calculat…
