Abstract
This chapter is devoted to some advanced methods for calculation of the heat kernel. Most of these methods are algebraic rather than analytic in nature, that is, instead of solving the heat equation directly we compute the heat semigroup; then the heat kernel is just the integral kernel of the heat semigroup. We also discuss basic concepts of path integrals.
