Title: Calabi-Yau manifolds -- Geometry meets modern physics again

Abstract: Calabi–Yau manifolds are important in superstring theory. In the most conventional superstring models, ten conjectural dimensions in string theory are supposed to come as four of which we are aware, carrying some kind of fibration with fiber dimension six. Essentially, Calabi–Yau manifolds are shapes that satisfy the requirement of space for the six "unseen" spatial dimensions of string theory, which may be smaller than our currently observable lengths as they have not yet been detected. In this talk, we will briefly go over some basics of Calabi-Yau manifolds and their relation with modern physics.
