This thesis consists of three parts all of which deal with questions related to scalar extensions and derived categories.<br /> In the first part we consider the question whether the conjugation of a complex projective K3 ...
This thesis is concerned with questions arising in the realm of mirror symmetry for K3 surfaces. It is divided into two parts.<br /> In the first part, we study the bijection between Fourier–Mukai partners of a K3 surface ...
