Weak omega-categories from intensional type theory [PDF]
We show that for any type in Martin-L\"of Intensional Type Theory, the terms of that type and its higher identity types form a weak omega-category in the sense of Leinster.

Semantics of Higher-Order Recursion Schemes [PDF]
Higher-order recursion schemes are recursive equations defining new operations from given ones called "terminals". Every such recursion scheme is proved to have a least interpreted semantics in every Scott's model of \lambda-calculus in which the ...

The fusion algebra of bimodule categories [PDF]
We establish an algebra-isomorphism between the complexified Grothendieck ring F of certain bimodule categories over a modular tensor category and the endomorphism algebra of appropriate morphism spaces of those bimodule categories.

Invertible defects and isomorphisms of rational CFTs [PDF]
Given two two-dimensional conformal field theories, a domain wall —or defect line— between them is called invertible if there is another defect with which it fuses to the identity defect.

Unifying Cubical Models of Univalent Type Theory [PDF]
We present a new constructive model of univalent type theory based on cubical sets. Unlike prior work on cubical models, ours depends neither on diagonal cofibrations nor connections.

Pseudo-dualizing complexes and pseudo-derived categories
The definition of a pseudo-dualizing complex is obtained from that of a dualizing complex by dropping the injective dimension condition, while retaining the finite generatedness and homothety isomorphism conditions.

Enriched Stone-type dualities [PDF]
A common feature of many duality results is that the involved equivalence functors are liftings of hom-functors into the two-element space resp. lattice.

Matlis category equivalences for a ring epimorphism
Under mild assumptions, we construct the two Matlis additive category equivalences for an associative ring epimorphism $u\colon R\to U$. Assuming that the ring epimorphism is homological of flat/projective dimension $1$, we discuss the abelian categories

A note on permutation twist defects in topological bilayer phases [PDF]
We present a mathematical derivation of some of the most important physical quantities arising in topological bilayer systems with permutation twist defects as introduced by Barkeshli et al. in cond-mat/1208.4834.

The co-stability manifold of a triangulated category [PDF]
Stability conditions on triangulated categories were introduced by Bridgeland as a 'continuous' generalisation of t-structures. The set of locally-finite stability conditions on a triangulated category is a manifold which has been studied intensively ...
