Abstract

In this paper we consider 2D Maxwell-dilaton gravity and calculate modified entropy due to higher order terms of the form ∑a n R n . We find that, higher order correction decreases the value of the black hole entropy. Then we compare the effect of higher order corrections with effect of Chern-Simons term on the black hole entropy and obtain the expansion coefficient a n .
