Research  (Dr. Petru Cioica-Licht)

My research is mainly concerned with the analysis of the regularity of stochastic partial differential equations (SPDEs) and consequences for their numerical approximation. I am rather driven by specifc questions than by particular techniques. Mathematically, I enjoy in particular the interplay of probability theory and analysis. So far, I have been mainly working on the following topics:

  • The development of a comprehensive Lp-theory for SPDEs on non-smooth domains, in particular, on polygons and polyhedra
  • The regularity analysis of SPDEs in specific scales of Besov spaces that determine the convergence rate of the best n-term approximation
  • The convergence analysis of numerical schemes for (S)PDEs
  • The analysis of stochastic Volterra-integral equations
