Seeley-DeWitt coefficients in \( \mathcal{N} \) = 2 Einstein-Maxwell supergravity theory and logarithmic corrections to \( \mathcal{N} \) = 2 extremal black hole entropy

We investigate the heat kernel method for one-loop effective action following the Seeley-DeWitt expansion technique of heat kernel with Seeley-DeWitt coefficients. We also review a general approach of computing the Seeley-DeWitt coefficients in terms of background or geometric invariants. We, then consider the Einstein-Maxwell theory em-bedded in minimal $$ \mathcal{N} $$ = 2 supergravity in four dimensions and compute the first three Seeley-DeWitt coefficients of the kinetic operator of the bosonic and the fermionic fields in an arbitrary background field configuration. We find the applications of these results in the computation of logarithmic corrections to Bekenstein-Hawking entropy of the extremal Kerr-Newman, Kerr and Reissner-Nordstrom black holes in minimal $$ \mathcal{N} $$ = 2 Einstein-Maxwell supergravity theory following the quantum entropy function formalism.
