摘要：

We use the M theory approach of Witten to investigate N = 1 SU(N-c) SQCD with N-f flavors. We reproduce the field theoretical results and identify in M theory the gluino condensate and the eigenvalues of the meson matrix, This approach allows us to identify the constant piece of the effective field theory coupling from which the coefficient of the one-loop beta-function can be identified, By studying the area of the M-theory five-brane we investigate the stability of type IIA brane configurations. We prove that in a supersymmetric setup there is no force between static D4-branes that end on NS five-branes, The force in the case that there is a relative velocity between the branes is computed. We show that at the regions of intersecting IIA branes the curvature of the M theory five-brane is singular in the type IIA limit. (C) 1997 Published by Elsevier Science B.V.
