Abstract:
We study vacua of N=1 SUSY gauge theory using conventional field theory 
tools as well as dual supergravity background. The Higgs vacua are dual 
to the mobile D3-branes which dissolve in the flavor D7-branes. Hence 
the moduli space of the world-volume gauge instantons on D7-branes 
should match the Higgs branch of the field theory. In case of N=2 
theories this relation is readily provided by the ADHM construction. In 
the N=1 case both sides of the duality are more complicated because of 
quantum corrections. We carefully analyze the case of the cascading N=1 
SU(N+M)xSU(N) theory and establish the agreement between the field 
theory and gravity.
