This Research School features four introductory courses on modern categorical algebra and its application to quantum theory. The goal is to provide a forum for graduate students and junior researchers to gain a strong technical foundation in this rich and dynamic area, and to meet some of the leading researchers in the area. There will also be many opportunities for networking with other students and researchers.
The school will feature four courses given by expert researchers from across the globe. Tutorial sessions given by expert teaching assistants will help participants learn the material. There will be many opportunities for informal interaction and networking.
Prerequisites. To get the most from the courses, participants should already have basic knowledge of category theory (categories, functors, natural transformations, isomorphisms, limits and colimits), and individual courses have further mild prerequisites given below.
Just as monoids have categories as a many-object generalisation, so
monoidal categories have a many-object generalisation, which are
Benabou's bicategories. This course will study bicategories in their
guise as many-object monoidal categories. Particular attention will be paid to the notion of enrichment in a
monoidal category or in a bicategory. Besides examining a range of
standard examples, we will also discuss how to set up bespoke
enrichments using the theory of free presentations of cocomplete
monoidal categories and bicategories.
Prerequisites: Basic category theory.
Teaching Assistant: Christina Vasilakopoulou, University of Patras
Hilbert spaces are the mathematical foundation of quantum theory. This course concerns the abstract structure of the monoidal dagger category they form. We identify conceptual ingredients for quantum computation, such as dual objects and Frobenius structures to model entanglement and measurement. Spatiotemporal structure is discussed not only via the graphical calculus, but also in terms of subunits and sheaves.
Prerequisites: Basic ideas about Hilbert spaces (adjoint operator, orthonormal basis, tensor product), basic ideas about point-set and pointless topology (topological space, frame, locales).

These lectures will motivate and explain finitary bicategories and their finitary birepresentations, their cell theory, the relationship between birepresentations and coalgebra 1-morphisms via the internal hom construction. This will be supported by explicit small examples and culminate in an extended example considering the categorification of Hecke algebras via Soergel bimodules.
Prerequisites: Basic representation theory of finite-dimensional algebras, for example the first few sections of Alex Bartel's notes.
Teaching Assistant: James MacPherson, University of East Anglia
We shall discuss the structure of Hopf algebras, focusing on classification problems in the finite dimensional and, in particular, in the semisimple case. Some of their main features and invariants will be discussed. We shall study the connection with tensor categories through their representation theory and discuss a number of applications and open problems.
Prerequisites: Algebras over fields, modules for algebras.
Teaching Assistant: Aryan Ghobadi, Queen Mary University of London
The conference will also feature a special research lecture.
Via different perspectives on braids we indicate how the search for topological invariants leads to crucial developments in representation theory and to speculations on higher topological invariants and TQFTs.
All sessions take place in the Roger Stevens Lecture Theatre 22 at the University of Leeds.

The lunch at the conference is provided by the university refectory. They can advise on the following allergens as ingredients in each food item: celery, gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, nuts, peanuts, sesame seeds, soya and sulphur dioxide. However, it is a conventional kitchen where all food and drinks are prepared in the same space, and so they cannot guarantee that any dish will not contain traces of any allergen.
