Higher-order Gaussian bounds for maximally subelliptic boundary value problems

Brian Street

We establish higher-order Gaussian upper bounds for the heat semigroups associated with a broad class of sectorial maximally subelliptic quadratic forms on manifolds with boundary.…

Non-uniqueness for a differential equation

Brian Street

Let $f (t, x), M (t, x) \in C ([0, 1]^{2})$ with $M (t, x) > 0$ . We consider differential equations of the form \[ \frac{\partial f}{\partial t}(t,x)=\frac{M(t,x)f(t,x)-M(t,0)f(t,0)}{x},\quad x>…
