Compactifying M-theory to four dimensions
We consider compactifications of M-theory to four-dimensional Minkowski space on seven-dimensional non-compact manifolds. These compactifications include a warp factor which is non constant due to the presence of sources coming from five-branes wrapping two-dimensional submanifolds of the internal seven-dimensional space. We derive the expression for the field strengths and consider an explicit...
متن کاملBPS-spectra in four dimensions from M-theory
I review my work together with Piljin Yi [1] on the spectrum of BPS-saturated states in N = 2 supersymmetric Yang-Mills theories. In an M -theory description, such states are realized as certain two-brane configurations. We first show how the central charge of the N = 2 algebra arises from the two-form central charge of the eleven-dimensional supersymmetry algebra, and derive the condition for ...
متن کاملNoncritical M-theory: Three Dimensions
At the macrosopic level we study candidate 3D effective field theories associated to M theory in three dimensions. These represent analogs of 11D supergravity for eleven dimensional M-theory. At the microscopic level we study various world volume (WV) theories that can be used to relate world sheet (WS) theories of two dimensional strings. These are better defined for 3D targets than their 11D ...
متن کاملChiral Gauge Theory in Four Dimensions
A formulation of abelian and non-abelian chiral gauge theories is presented together with arguments for the unitarity and renormalisability in four dimensions.
متن کاملMaier-Saupe theory in four dimensions.
Maier-Saupe theory is the canonical mean field description of thermotropic nematic liquid crystals. In this paper, we examine the predictions of the theory in four spatial dimensions. Representations of the order parameter tensor and the existence of new phases are discussed. The phase diagram, based on numerical solution of the self-consistent equations and Landau theory, is presented. Orienta...
