摘要：A quantum groupoid is a mathematical structure that generalizes a groupoid and a quantum group at the same time. In this talk, I will present the motivations and the state of the art of the theory of quantum groupoids from the point of view of operator algebras. First, I will discuss the motivations behind the interest in the study of quantum groupoids, then I will present a brief overview of the current theory of quantum groupoids. If time permits, I will explain how quantum groupoids arise from inclusions of von Neumann algebras following a procedure à la Galois.
