Some Unexplored Topics in The Reconstruction of Scalar Parameters of Subdiffusion

Sergii V. Siryk, Lidiia Tereshchenko, Nataliya Vasylyeva

In the paper, we discuss the reconstruction of scalar parameters in a linear diffusion equation with fractional in time differential operators and with additional nonlocal (convolu…

On the explicit formula linking a function to the order of its fractional derivative

Vasyl Semenov, Nataliya Vasylyeva

In this paper, given a certain regularity of a function , we derive an explicit formula relating the order of the leading fractional derivative in a fractional di…

Regularized Reconstruction of Scalar Parameters in Subdiffusion with Memory via a Nonlocal Observation

Andrii Hulianytskyi, Sergei Pereverzyev, Sergii Siryk +1

In the paper, we propose an analytical and numerical approach to identify scalar parameters (coefficients, orders of fractional derivatives) in the multi-term fractional differenti…

On a local solvability of the contact Muskat problem

Nataliya Vasylyeva

In the paper, we discuss the two-dimensional contact Muskat problem with zero surface tension of a free boundary. The initial shape of the unknown interface is a smooth simple curv…

Analysis of a Radiotherapy Model for Brain Tumors

Marina Chugunova, Hangjie Ji, Roman Taranets +1

In this work, we focus on the analytical and numerical study of a mathematical model for brain tumors with radiotherapy influence. Under certain assumptions on the given data in th…
