Estimates of gradient of -harmonic functions for nonlocal operators with order
Tomasz Grzywny, Tomasz Jakubowski, Grzegorz Żurek
We obtain Grönwall type estimates for the gradient of the harmonic functions for a Lévy operator with order strictly larger than 1 and minimal assumptions of its Lévy measure.
Green function for gradient perturbation of unimodal Lévy processes in the real line
T. Grzywny, T. Jakubowski, G. Żurek
We prove that the Green function of a generator of symmetric unimodal Lévy processes with the weak lower scaling order bigger than one and the Green function of its gradient pertur…
Machine learning methods for accurate delineation of tumors in PET images
Jakub Czakon, Filip Drapejkowski, Grzegorz Zurek +3
In oncology, Positron Emission Tomography imaging is widely used in diagnostics of cancer metastases, in monitoring of progress in course of the cancer treatment, and in planning r…
