Space-time non-commutativity tends to create bound states
D. V. Vassilevich, A. Yurov
We study the spectrum of fluctuations about static solutions in 1+1 dimensional non-commutative scalar field models. In the case of soliton solutions non-commutativity leads to cre…
Cohomological extension of Spin(7)-invariant super Yang-Mills theory in eight dimensions
D. M"ulsch, B. Geyer
It is shown that the Spin(7)-invariant super Yang-Mills theory in euight dimensions, which relies on the existence of the Caley invariant, permits the construction of a cohomologic…
G_2 invariant 7D Euclidean super Yang-Mills theory as a higher-dimensional analogue of the 3D super-BF theory
D. M"ulsch, B. GEyer
A formulation of the N_T=1, D=8 Euclidean super Yang-Mills theory with generalized self-duality and reduced Spin(7)-invariance is given which avoids the peculiar extra constraints…
Superfield extended BRST quantization in general coordinates
B. Geyer, D. M. Gitman, P. M. Lavrov +1
We propose a superfield formalism of Lagrangian BRST-antiBRST quantization of arbitrary gauge theories in general coordinates with the base manifold of fields and antifields desrib…
Non-commutative heat kernel
D. V. Vassilevich
We consider a natural generalisation of the Laplace type operators for the case of non-commutative (Moyal star) product. We demonstrate existence of a power law asymptotic expansio…
Chiral anomaly for local boundary conditions
V. N. Marachevsky, D. V. Vassilevich
It is known that in the zeta function regularization and in the Fujikawa method chiral anomaly is defined through a coefficient in the heat kernel expansion for the Dirac operator.…
