On the p(x)-Laplace Equation in Carnot Groups
by Freeman, Robert D., Ph.D., University of South Florida, 2020, 88; 27743202
Abstract (Summary)

In this thesis, we examine the p(x)-Laplace equation in the context of Carnot groups. The p(x)-Laplace

equation is the prototype equation for a class of nonlinear elliptic partial differential equations having so-called

nonstandard growth conditions. An important and useful tool in studying these types of equations is

viscosity theory. We prove a p()-Poincar´e-type inequality and use it to prove the equivalence of potential

theoretic weak solutions and viscosity solutions to the p(x)-Laplace equation. We exploit this equivalence

to prove a Rad´o-type removability result for solutions to the p-Laplace equation in the Heisenberg group.

Then we extend this result to the p(x)-Laplace equation in the Heisenberg group.
