This article continues to study the linearized Chandrasekhar equation. We use the Hilbert-type inequalities to accurately calculate the norm of the Fredholm integral operator and obtain the exact range for the parameters of the linearized Chandrasekh

In this paper, we study a class of ultraparabolic operators of Kolmogorov type by Hamiltonian formalism. Geodesics induced by the operators are explicitly calculated. By means of the theory of path integrals, we derive the heat kernel of Kolmogorov-t

In this paper, we study a class of degenerate elliptic operators with quadratic potentials by Hamiltonian formalism. Geodesics induced by the operators are explicitly characterized. With the help of a probabilistic ansatz, we generalize our kernel fo

This paper is focused on the approximate procedures for the periodic solutions of the nonlinear Hamilton equation with Gaussian potential. We propose a modified rational harmonic balance method to treat conservative nonlinear equations without the re

In this paper, we study Ornstein–Uhlenbeck operators with quadratic potentials. We use Hamiltonian formalism to characterize the singularities produced by the potentials by finding explicit geodesics which are induced by the operators. Then we obta
