The Non-Perturbative SUSY Yang-Mills Theory from Semiclassical Absorption of Supergravity by Wrapped D Branes
The imaginary part of the two point functions of the superconformal anomalous
currents are extracted from the cross-sections of semiclassical absorption of
dilaton, RR-2 form and gravitino by the wrapped D5 branes. From the central
terms of the two point functions anomalous Ward identity is established which
relates the exact pre-potential of the SUSY Yang-Mills theory with
the vacuum expectation value of the anomaly multiplet. From the Ward identity,
WDVV (Witten-Dijkgraaf-Verlinde-Verlinde) equation can be derived which is
solved for the exact pre-potential.Comment: 11 pages, late
O(a) Perturbative improvement for Wilson fermions
The coefficient of the O(a)-improved
Sheikholeslami-Wohlert action for Wilson fermions are perturbatively
determined at one-loop level and estimated at two-loop level.Comment: 8-pages + (two pages of Fig.s) MPI-ph/93-2
Deriving exact prepotential for supersymmetric Yang-Mills theories from superconformal anomaly with rank two gauge groups
The exact prepotential for supersymmetric Yang-Mills theory is
derived from the superconformal anomalous Ward identity for the gauge group
SU(2) and SU(3) which can be generalized to any other rank two gauge group.Comment: Latex file, 14 Pages, some minor changes, References added

The Gravity dual of the Non-Perturbative SUSY Yang-Mills Theory
The anomalous Ward identity is derived for SUSY Yang-Mills theories,
which is resulted out of Wrapping of branes on Supersymmetric two cycles.
From the Ward identity One obtains the Witten-Dijkgraaf-Verlinde-Verlinde
equation and hence can solve for the pre-potential. This way one avoids the
problem of enhancon which maligns the non-perturbative behaviour of the
Yang-Mills theory resulted out of Wrapped branes.Comment: 4 pages, LaTeX. Talk given at the IXth International Symposium on
Particles, Strings and Cosmology PASCOS '03, Mumbai-India, January 3-8 2003.
