Heat Kernel Asymptotics of Zaremba Boundary Value Problem
Ivan Avramidi
The Zaremba boundary-value problem is a boundary value problem for Laplace-type second-order partial differential operators acting on smooth sections of a vector bundle over a smoo…

A discrete leading symbol and spectral asymptotics for natural differential operators
Ivan Avramidi, Thomas Branson
We initiate a systematic study of natural differential operators in Riemannian geometry whose leading symbols are not of Laplace type. In particular, we define a discrete leading s…
