چکیده
We consider dimensionally reduced three-dimensional supersymmetric Yang– Mills-Chern–Simons theory. Although the N = 1 supersymmetry of this theory does not allow true massive Bogomol'nyi–Prasad–Sommerfield (BPS) states, we find approximate BPS states which have non-zero masses that are almost independent of the Yang–Mills coupling constant and which are a reflection of the massless BPS states of the underlying N = 1 super Yang–Mills theory. The masses of these states at large Yang–Mills coupling are exactly at the n-particle continuum thresholds. This leads to a relation between their masses at zero and large Yang–Mills coupling.

Based on results about open string correlation functions, a nonassociative algebra was proposed in a recent paper for D-branes in a background with nonvanishing H. We show that our associative algebra obtained by quantizing the endpoints of an open string in an earlier work can also be used to reproduce the same correlation functions. The novelty of this algebra is that functions on the D-brane...

Starting from N = 1 scalar supermultiplets in 2+1 dimensions, we build explicitly the composite superpartners which define a N = 2 superalgebra induced by the initial N = 1 supersymmetry. The occurrence of this extension is linked to the topologically conserved current out of which the composite superpartners are constructed.

We construct explicit solutions of the Hermitian Yang-Mills equations on the noncommutative space C θ . In the commutative limit they coincide with the standard instantons on CP written in local coordinates.

We present two examples of SUSY mechanics related with Kähler geometry. The first system is the N = 4 supersymmetric one-dimensional sigma-model proposed in hep-th/0101065. Another system is the N = 2 SUSY mechanics whose phase space is the external algebra of an arbitrary Kähler manifold. The relation of these models with antisymplectic geometry is discussed.

We investigate vortex solutions to the Abelian Higgs field equations in a four dimensional de Sitter spacetime background. We obtain both static and dynamic solutions with axial symmetry that are generalizations of the Nielsen-Olesen gauge vortices in flat spacetime. The static solution is located in the static patch of de Sitter space. We numerically solve the field equations in an inflationar...
