Summary: In this study, the relationship between commutative algebras in braided tensor categories and braid-reversed tensor equivalences is explored, based on the representation theory of vertex algebras. By providing a detailed account of canonical algebra construction in the Deligne product, it is shown that under certain conditions, braid-reversed equivalences exist in specific simple algebraic structures.

Summary: This article discusses the relationship between vertex operator algebras and the category of grading-restricted generalized modules, and gives conditions under which the category inherits semisimplicity from the A-module category. Furthermore, these results are generalized to the case of vertex operator superalgebras.

Summary: This paper proves the trialities among eight families of W-(super)algebras of types B, C, and D and provides a new interpretation of coset realizations. In terms of specific applications, the rationality of various vertex superalgebras and principal W-algebras is established.

Summary: This work introduces Urod algebras associated with simply laced Lie algebras and the concept of translation of W-algebras. The key results are derived by showing the commutation between quantum Hamiltonian reduction and tensoring with integrable representations. The work also presents new constructions of automorphisms of vertex algebras, which have independent interest. The applications of this work include fusion categories of modules of exceptional W-algebras and the construction of corner vertex algebras. The representation theoretic interpretation of the Nakajima-Yoshioka blowup equations for the moduli space of framed torsion free sheaves on CP2 is one of the major motivations.

Summary: This paper proves Feigin-Frenkel type dualities between subregular W-algebras of type A and principal W-superalgebras of type B, as well as between the principal W-superalgebras of types sl(1 | n) and osp(2 | 2n). The results include isomorphisms of Heisenberg cosets at dual levels, and a novel Kazama-Suzuki type coset construction. Additionally, it is shown that the simple principal W-superalgebra and its Heisenberg coset are rational and/or C-2-cofinite under certain conditions.
