I do mostly geometry and topology, with an analytic bias. For the past few years Morse theory has popped up in my research, but not in a conventional way.

What is “tilting” in the context of large deviations?
There is a brief discussion of tilting in section 23.4 of Klenke's book Probability Theory. A Comprehensive Course, Springer Verlag, 2008.

Topological degree and polynomial degree
@ Edson. I fixed an omission in my proof. You can get more interesting answers if in my proof you choose $K$ to be a knot disjoint from $C$ and having large linking number with $C$. I believe that $T$ as defined by you is equal to this likinking number.

If there is a diffeomorphism between two surfaces, what is the relation between LaplaceBeltrami operators on the surfaces?
The answer is not pretty.
