Singular Adams inequality for biharmonic operator on Heisenberg Group and its applications
The goal of this paper is to establish singular Adams type inequality for biharmonic operator on Heisenberg group. As an application, we establish...

Nonexistence results for a class of evolution equations in the Heisenberg group
We establish a nonexistence result of global solutions to the nonlinear evolution equation (uβ)tt − ϑαHΔH(uβ) + h(ϑ)(uq)t = f(t, ϑ)up + w(t, ϑ), ϑ ∈...

Higher-Order Multilinear Poincaré and Sobolev Inequalities in Carnot Groups
The notions of higher-order weighted multilinear Poincaré and Sobolev inequalities in Carnot groups are introduced. As an application, weighted...

Large time behavior for the heat equation on Carnot groups
We first generalize a decomposition of functions on Carnot groups as linear combinations of the Dirac delta and some of its derivatives, where the...

Extension problem and fractional operators: semigroups and wave equations
We extend results of Caffarelli–Silvestre and Stinga–Torrea regarding a characterization of fractional powers of differential operators via an...

Regularity lifting of weak solutions for nonlinear sub-Laplace equations on homogeneous groups
Let G be a homogeneous group, and let X 1 , X 2 , … , X m be left invariant real vector fields being homogeneous of degree one on G . We consider the...

Blaschke, Privaloff, Reade and Saks Theorems for Diffusion Equations on Lie Groups
We prove some asymptotic characterizations for the subsolutions to a class of diffusion equations on homogeneous Lie groups. These results are the...
