Description
In this talk we consider static, extremal and spherically symmetric black hole solution of general Maxwell-Einstein-scalar (1+3)d theory with no scalar potential. We show that the effective one dimensional action, from which the effective black hole potential is usually computed, is the one dimensional effective Routhian of the original (1+3)d action. We further discuss this Routhian framework is equivalent to the Sen entropy functional approach, enabling one to compute the black hole entropy.
