DOI: 10.1007/s00158-019-02441-1
Abstract: It is common for papers on surrogate fitting to select test functions for testing algorithms. This raises the issue of how well the algorithms generalize to other functions. This editorial proposes as a possible complement… read more here.

DOI: 10.1007/s10915-017-0369-z
Abstract: We develop an ultra-weak variational formulation of a fractional advection diffusion problem in one space dimension and prove its well-posedness. Based on this formulation, we define a DPG approximation with optimal test functions and show… read more here.

DOI: 10.1016/j.jksus.2016.09.011
Abstract: Abstract The paper develops a weak-form integral equation method (WFIEM) for solving the singularly perturbed convection–diffusion equation, which is too ill-posed to find the singular solution using conventional methods. We use Green’s second identity to… read more here.
