Congratulations to Hidde Schönberger for receiving the Graduate School of Natural Sciences Master's Thesis Award! This prize is handed out every year for the best Master's thesis written at the Faculty of Science at Utrecht University.
With his thesis, "Characterization of Lower Semicontinuity and Relaxation of Fractional Integral and Supremal Functionals," Hidde Schönberger closes a gap in the literature regarding the existence theory for a class of variational problems involving fractional derivatives. Besides their mathematical significance, these problems have different applications in materials science and image processing. The scientific contributions of the thesis have lead to a publication in the journal Nonlinear Analysis and are, in the eyes of the jury, "a work any experienced researcher can be proud of, let alone a Master's student."
The thesis project was supervised by Prof. Dr. Carolin Kreisbeck, who is now also his Ph.D. advisor at KU, where he is continuing his research on nonlocality in the calculus of variations at the Chair of Analysis.
