Grażyna Krech

Grażyna Krech, Ph.D., serves as an Assistant Professor at the Department of Mathematical Analysis and Applications within the Faculty of Applied Mathematics at AGH University of Science and Technology in Kraków, Poland. Her primary responsibilities include teaching duties and active research in mathematical analysis, with office locations documented in both Building C-7 (Czarnowiejska 36, Room 615) and Building B-7 (Czarnowiejska 70, Room 35), the latter being her current consultation venue for the winter semester 2021/22.

Her research centers on classical approximation theory, specifically investigating:

• Rate of convergence for linear operators
• Voronovskaya type asymptotic theorems
• Boundary value problems
• Approximation properties of Poisson integrals
• Behavior of positive linear operators

Her work frequently employs Hermite and Laguerre polynomial systems, Gamma operators, and Durrmeyer-type constructions across univariate and bivariate function spaces.

Analysis of her 15 most recent publications (2013-2018) reveals a cohesive research program focused on quantitative approximation theory. She consistently develops direct and converse results for operator sequences in L^p and exponential weighted spaces, with particular emphasis on convergence rates and asymptotic behavior. Her contributions bridge classical analysis and numerical methods, maintaining strong theoretical rigor while addressing practical approximation challenges through Poisson integrals and specialized operator families.

No scientific awards or major honors are documented in the available materials.

Information regarding student supervision, grant funding, or collaborative research teams was not included in the source documents, though her active conference participation suggests engagement with the approximation theory community. Her consultation schedule indicates direct student interaction during academic semesters.
