Seminarium KMMF "Teoria Dwoistości"

Critical points of variational functionals describe a widerange of real life phenomena. The typical approach to tackle them is viathe limits of families of approximate problems. I would like to discussapproximation in unconventional function spaces that is useful in thecalculus of variations, focusing on when and why it may be impossible. Iwill also show when it is feasible and how to use it.
