Analytic solutions of the Teukolsky equation in Kerr geometries are presented in the form of series of hypergeometric functions and Coulomb wave functions. Relations between these solutions areâ€¦ (More)

Recently, Schnabl constructed the analytic solution of the open string tachyon. Subsequently, the absence of the physical states at the vacuum was proved. The development relies heavily on the use ofâ€¦ (More)

Recently proposed mechanism of the black hole condensation at conifold singularity in type II string is an interesting idea from which we can interpret the phase of the universal moduli space of theâ€¦ (More)

We derive the superpotential of gauge theories having matter fields in the fundamental representation of gauge fields by using the method of Dijkgraaf and Vafa. We treat the theories with one flavourâ€¦ (More)

It is well known that the perturbation equations of massless fields for the Kerr-de Sitter geometry can be written in the form of separable equations. The equations have five definite singularitiesâ€¦ (More)

We analyze the relation between a topological coset model based on super SL(2, R)/U(1) coset and non-critical string theory by using free field realization. We show that the twisted N = 2 algebra ofâ€¦ (More)

We discuss how to obtain the superpotential of the baryons and mesons for SU(N) gauge theories with N flavour matter fields from matrix integral. We apply the mean-field approximation for the matrixâ€¦ (More)

The analytic solution of Teukolsky equation in Kerr-de Sitter and Kerr-Newmande Sitter geometries is presented and the properties of the solution are examined. In particular, we show that ourâ€¦ (More)

Analytic solutions of the Regge-Wheeler equation are presented in the form of series of hypergeometric functions and Coulomb wave functions which have different regions of convergence. Relationsâ€¦ (More)

We show how to give the expression for periods, Higgs field and its dual of N = 2 supersymmetric Yang-Mills theory around the conformal point. This is achieved by evaluating the integralâ€¦ (More)
