Regularization of Functional Determinants of Radial Operators via Heat Kernel Coefficients
Yutaro Shoji, Masahide Yamaguchi
We propose an efficient regularization method for functional determinants of radial operators using heat kernel coefficients. Our key finding is a systematic way to identify heat k…
