Applied and Numerical Analysis Research Group

The Applied and Numerical Analysis (ANA) group is focused on the analysis of mathematical models of biological, chemical or physical processes described by differential, integral and integro-differential equations, and in the development, analysis and implementation of numerical methods for their approximate solutions. 

The diverse applications considered by the group include rigorous analysis and computational modelling of problems in acoustic, elastic and electromagnetic wave propagation, modelling of fluid flows, biological processes, viscoelasticity and fracture in solids. Novel finite element and boundary element methods are developed and analysed for these applications, leading to robust algorithms and specialised software. A related research topic is approximation of orthogonal polynomials and special functions with explicit error terms. 

The group research also includes analysis of nonlinear problems, like Navier-Stokes system, Gierer-Meinhardt system, and abstract bifurcation problems. 

The ANA group is home of a major international collaboration on analytical and numerical methods for boundary-domain integral equations, aimed at creating a new method for analysis and solution of variable-coefficient and nonlinear PDEs.
