A new method is proposed for heat kernel expansion in curved space, without using the recursion relation. The existence of the resummed form of nonderivative terms arising out of X from the operator A = -□ + X is proved. The De Witt-Seeley-Gilkey coefficients E<sub>2</sub>(x) and E<sub>4</sub>(x) are derived.
