The research group was founded on July 1, 2012. It is supported by the Hungarian Academy of Sciences and it is hosted at the Eötvös Loránd University in Budapest.

The main objective of the group is to provide the theoretical background in numerical mathematics, being extremely important in technical and industrial applications, and to gather scientists working in this field.

Numerical methods providing approximative solutions to systems of partial differential equations are needed in various fields of science. Our research group investigates elliptic, parabolic, and hyperbolic problems by applying already existing and new tools as well, such as iterative methods based on preconditioning operators, discontinuous finite element methods, techniques from operator semigroup theory, operator splitting procedures, exponential and Magnus integrators, and Richardson extrapolation. The new methods developed are then implemented to examples modelling real-life phenomena, e.g., air pollution transport models, fuel cell models, Maxwell equations, shallow water equations.

Analysis of evolutionary problems on complex networks play an important role in the work of the research group. Modelling of network processes by systems of differential equations serves as a link to the previous topic. The aim of this line of research is to explore the characteristics obtained from the structure of the network, to ensure the efficient solvability of the equations, and to investigate the reliability of the networks.
