interests
My interests include:
- regularity properties of minimizers (etc.) with non-standard growth (ie. generalized Orlicz / Musielak-Orlicz spaces, variable exponent Lebesgue spaces)
- the theory and applications of variable exponent analysis
- image processing
- more generally: calculus of variations, geometric analysis, potential theory and nonlinear partial differential equations
Currently I'm working on:
- boundedness and other properties of the spherical maximal operator, with P. Górka (Warsaw Polytechnic)
- boundary Harnack inequalities and eigenvalue problems in generalized settings (Orlicz, variable Lebesgue, generalized Orlicz), with T. Adamowicz (Institute of Math., Polish Acad. of Sciences) and N. Lundström (Umeå)
My future plans include:
- More on generalized Orlicz spaces
- More on image processing, in either variable exponent or generalized Orlicz settings; possibly on the existence/regularity of minimizers
