Abstract: In this paper, we will construct new examples of derived equivalent Calabi--Yau 3-folds with Picard number greater than one. We also study their mirror Calabi--Yau manifolds and find that they are given by Schoen's fiber…

Abstract: We settle a question that originates from results and remarks by Koll\'ar on extremal ray in the minimal model program: In positive characteristics, there are no Mori fibrations on threefolds with only terminal singularities whose…

Abstract: We classify finite p-groups acting minimally on real del Pezzo surfaces. This gives a partial classification of p-subgroups in the real plane Cremona group.
