Published in 2017 at "Mathematische Nachrichten"

DOI: 10.1002/mana.201400347

Abstract: We provide several equivalent characterizations for the upper doubling condition introduced in the framework of T. Hytonen for non-homogeneous metric measure spaces. We also introduce the “smooth strong upper doubling” condition and provide equivalent characterizations,… read more here.

Published in 2022 at "Mathematische Zeitschrift"

DOI: 10.1007/s00209-022-02976-y

Abstract: We present ten different characterizations of functions satisfying a weak reverse Hölder inequality on an open subset of a metric measure space with a doubling measure. Among others, we describe these functions as a class… read more here.

DOI: 10.1007/s00209-022-02987-9

Abstract: We prove that the domain of the local Dirichlet form is strictly contained in the domain of any stable-like non-local Dirichlet form on general metric measure spaces. read more here.

DOI: 10.1007/s10476-024-00030-z

Abstract: We explore boundedness properties of some natural operators of convolution type in the context of metric measure spaces. Their study is suggested by certain transformations used in computer vision. read more here.

Published in 2025 at "Journal of Mathematical Sciences"

DOI: 10.1007/s10958-025-07910-1

Abstract: In the article, we study variational eigenvalues on doubling metric measure spaces. We prove the existence of minimizers of variational Neumann (p, q)-eigenvalues on metric measure spaces, and on this base, we obtain estimates of Neumann… read more here.

Published in 2019 at "Israel Journal of Mathematics"

DOI: 10.1007/s11856-019-1865-7

Abstract: We consider a “convolution mm-Laplacian” operator on metric-measure spaces and study its spectral properties. The definition is based on averaging over small metric balls. For reasonably nice metric-measure spaces we prove stability of convolution Laplacian’s… read more here.

Published in 2018 at "Forum Mathematicum"

DOI: 10.1515/forum-2018-0016

Abstract: In this work, we are concerned with the study of the N-Lusin property in metric measure spaces. A map satisfies that property if sets of measure zero are mapped to sets of measure zero. We… read more here.
