Comments on Supersymmetric Vector and Matrix Models
نویسنده
چکیده
Some results in random matrices are generalized to supermatrices, in particular superma-trix integration is reduced to an integration over the eigenvalues and the resulting volume element is shown to be equivalent to a one dimensional Coulomb gas of both positive and negative charges.It is shown that,for polynomial potentials, after removing the instability due to the annihilation of opposite charges, supermatrix models are indistinguishable from ordinary matrix models, in agreement with a recent result by Alvarez-Gaumè and Mañes. It is pointed out however that this may not be true for more general potentials such as for instance the supersymmetric generalization of the Penner model.

Comments on Thermodynamics of Supersymmetric Matrix Models
We present arguments that the structure of the spectrum of the supersymmetric matrix model with 16 real supercharges in the large N limit is rather nontrivial, involving besides the natural energy scale ∼ λ1/3 = (g2N)1/3 also a lower scale ∼ λ1/3N−5/9. This allows one to understand a nontrivial behaviour of the mean internal energy of the system E ∝ T 14/5 predicted by AdS duality arguments.
متن کاملComments on Effective Superpotentials via Matrix Models
Dijkgraaf and Vafa have conjectured that the effective superpotentials for N = 1 four-dimensional supersymmetric gauge theories can be given by the planar diagrams of matrix models. We examine some special models with cubic and quartic tree level superpotentials for adjoint chiral superfield Φ. We consider the effective superpotentials for the classical vacuum Φ = 0 for U(N) and SO(N)/Sp(N) gau...
متن کاملComments on N = ( 2 , 2 ) supersymmetry on two - manifolds
We study curved-space rigid supersymmetry for two-dimensional N = (2, 2) supersymmetric fields theories with a vector-like R-symmetry by coupling such theories to background supergravity. The associated Killing spinors can be viewed as holomorphic sections of particular complex line bundles over Euclidean space-time, which severely restricts the allowed supersymmetric couplings on compact orien...
متن کاملDetermination of weight vector by using a pairwise comparison matrix based on DEA and Shannon entropy
The relation between the analytic hierarchy process (AHP) and data envelopment analysis (DEA) is a topic of interest to researchers in this branch of applied mathematics. In this paper, we propose a linear programming model that generates a weight (priority) vector from a pairwise comparison matrix. In this method, which is referred to as the E-DEAHP method, we consider each row of the pairwise...
متن کاملHarmonic Superfields in N = 4 Supersymmetric Quantum Mechanics
This is a brief survey of applications of the harmonic superspace methods to the models of N = 4 supersymmetric quantum mechanics (SQM). The main focus is on a recent progress in constructing SQM models with couplings to the background non-Abelian gauge fields. Besides reviewing and systemizing the relevant results, we present some new examples and make clarifying comments.
