摘要
We consider the Schrödinger type operator (1 + | x| α) Δ + c| x| α - 2, for α> 2 , c< 0 and N> 2. Heat kernel estimates of the associated semigroup are obtained using the equivalence between weighted Nash inequalities and “weighted” ultracontractivity of a symmetric Markov semigroup. Moreover we give estimates of the eigenfunctions of the operator for large values of |x|. © 2016, Università degli Studi di Napoli Federico II"."
