The linear relations between the complex moduli and using the linear relations reduce the stabilization equations for supersymmetric black holes in N=2 theory

Abstract

In [Phys. Rev. D 54, 6293 (1996)], the black hole entropy was derived by solving the matrix equation obtained from the stabilization equations for the solution of frozen moduli. In this paper, by directly solving the stabilization equations for the solution of frozen moduli without using the matrix equation, we find linear relations between any two of the three complex moduli at the black hole horizon. So far, no one discusses the linear relations. Via the linear relations, we derive the unique solution of frozen moduli and reduce the stabilization equations in three different ways. For example, the eight stabilization equations in [Phys. Rev. D 54, 6293 (1996)] can be replaced equivalently with three equations: the solution of moduli z1 and two linear relations, which are much simpler and more intuitive.
