Kolmogorov equations perturbed by an inverse-square potential
, 2011 In this paper we present a nonexistence result of exponentially bounded positive solutions to a parabolic equation of Kolmogorov type with a more general drift term perturbed by an inverse square potential. This result generalizes the one obtained in [8].

Linear and semilinear problems involving $Delta_lambda$-laplacians
, 2018 In recent years a growing attention has been devoted to ∆λ-Laplacians, linear second-order degenerate elliptic PDO’s contained in the general class introduced by Franchi and Lanconelli in some papers dated 1983–84 [12, 13, 14].

Time-domain criteria for the L2-stability of nonstationary feedback systems
, 1973 Criteria for the L2-stability of linear and nonlinear time-varying feedback systems are given. These are conditions in the time domain involving the solution of certain associated matrix Riccati equations and permitting the use of a very general class of

Periodic solutions for nonlinear systems of Ode's with generalized variable exponents operators
Ordinary and partial differential equations with operators containing the p-Laplace operator, the so called phi-Laplace operator, operators with variable exponents and the double phase operators have been studied thoroughly for at least the last 20 years
