Stability of solutions of semilinear evolution equations with integro-differential operators

Andrzej Rozkosz, Leszek Słomiński

We consider solutions of the Cauchy problem for semilinear equations with (possibly) different Lévy operators. We provide various results on their convergence under the assumption…

Nonlinear Hardy-Stein type identities for harmonic functions relative to symmetric integro-differential operators

Tomasz Klimsiak, Andrzej Rozkosz

We show identities of Hardy-Stein type for harmonic functions relative to integro-differential operators corresponding to general symmetric regular Dirichlet forms satisfying the a…

Robin problem with measure data and singular nonlinearities on the boundary

Andrzej Rozkosz

We consider the Robin problem for a uniformly elliptic divergence operator with measure data on the right-hand side of the equation and an absorption term on the boundary involving…

Reflected Skorokhod equations and the Neumann boundary value problem for elliptic equations with Levy-type operators

Andrzej Rozkosz, Leszek Slominski

We consider Neumann problem for linear elliptic equations involving integro-differential operators of Levy-type. We show that suitably defined viscosity solutions have probabilisti…

Dirichlet problem for semilinear partial integro-differential equations: the method of orthogonal projection

Tomasz Klimsiak, Andrzej Rozkosz

We study the Dirichlet problem for semilinear equations on general open sets with measure data on the right-hand side and irregular boundary data. For this purpose we develop the c…
