A Hamiltonian Approach to the Heat Kernel of a SubLaplacian on S(2n+1) (1303.0457v1)
Published 3 Mar 2013 in math.AP, math.CA, math.CV, and math.DG
Abstract: The heat kernel for the Cauchy-Riemann subLaplacian on S(2n+1) is derived in a manner which is completely analogous to the classical derivation of elliptic heat kernels. This suggests that the classical hamiltonian construction of elliptic heat kernels, with appropriate modifications, does yield heat kernels for subelliptic operators.
