报告摘要：The concepts of symmetry and duality play a pivotal role in representation theory. We will examine how these notions can be formulated in the context of monoidal categories, and even monoidal supercategories. We will begin by introducing the technique of string diagrams. Then we will examine the possible types of dualities and symmetries that can arise in monoidal (super)categories, using intuitive diagrammatic arguments to deduce some of their basic properties. All of this will lead us naturally to oriented and unoriented Brauer categories, which are intimately related to the representation theory of Lie (super)groups.
