Abstract

Let XX be a smooth, compact, projective K\"ahler variety and DD be a divisor of a holomorphic form FF, and assume that DD is smooth up to codimension two. Let ω\omega be a K\"ahler form on XX and KXK_{X} the corresponding heat kernel which is associated to the Laplacian that acts on the space of smooth functions on XX. Using various integral transforms of KXK_{X}, we will construct a meromorphic function in a complex variable ss whose special value at s=0s=0 is the log-norm of FF with respect to μ\mu. In the case when XX is the quotient of a symmetric space, then the function we construct is a generalization of the so-called elliptic Eisenstein series which has been defined and studied for finite volume Riemann surfaces.
