A new preprint of Matthias Erhardt was published — marking the beginning of a promising German–Indian research collaboration!

Together with colleagues from Department of Mathematical Sciences, Indian Institute of Technology (IIT) (BHU) Varanasi and the University of Wuppertal they present:
“Alikhanov–XfPINNs: Adaptive Physics-Informed Learning for Nonlinear Fractional PDEs on Nonuniform Meshes”. Link: (PDF) Alikhanov-XfPINNs: Adaptive Physics-Informed Learning for Nonlinear Fractional PDEs on Nonuniform Meshes

This work introduces a new framework combining:

  • adaptive physics-informed neural networks (PINNs)
  • high-order fractional discretization
  • nonuniform temporal meshes
  • accelerated treatment of memory effects in fractional PDEs

Our goal is to bridge modern scientific machine learning with robust numerical analysis for challenging nonlinear fractional PDEs. This preprint represents a first step in a broader series of German–Indian cooperation activities in applied mathematics, scientific computing, and AI-enhanced PDE modeling.
