The inverse, the heat semigroup, Liouville's theorems and the spectrum for the Grushin operator
The authors give new Sobolev estimates for the inverse and the heat semigroup of the Grushin operator \(G\) on \(\mathbb R^2\). Moreover, they give Liouville theorems and compute the spectrum of the Grushin operator \(G\) by transforming it into a family of parametrized Hermite operators.
