چکیده
We construct an RG potential for N = 2 supersymmetric SU(2) Yang-Mills theory, and extract a positive definite metric by comparing its gradient with the recently discovered beta-function for this system, thus proving that the RG flow is gradient in this four-dimensional field theory. We also discuss how this flow might change after supersymmetry breaking, provided the quantum symmetry group does not, emphasizing the non-trivial problem of asymptotic matching of automorphic functions to perturbation theory.

Spacetime superalgebras with 64 or less number of real supercharges, containing the type IIB Poincaré superal-gebra in (9, 1) dimensions and the N = 1 Poincaré superalgebra in (10, 1) are considered. The restriction D ≤ 14, and two distinct possibilities arise: The N = (1, 0) superalgebra in (11, 3) dimensions, and the N = (2, 0) super-algebra in (10, 2) dimensions. Emphasizing the former, we d...

Abstract. SU(N) Yang-Mills integrals form a new class of matrix models which, in their maximally supersymmetric version, are relevant to recent non-perturbative definitions of 10-dimensional IIB superstring theory and 11-dimensional M-theory. We demonstrate how Monte Carlo methods may be used to establish important properties of these models. In particular we consider the partition functions as...
