Drinfeld Center and Representation Theory for Monoidal Categories [PDF]

open access: greenCommunications in Mathematical Physics, 2016
Motivated by the relation between the Drinfeld double and central property (T) for quantum groups, given a rigid C*-tensor category C and a unitary half-braiding on an ind-object, we construct a *-representation of the fusion algebra of C. This allows us to present an alternative approach to recent results of Popa and Vaes, who defined C*-algebras of ...

The center of monoidal 2-categories in 3+1D Dijkgraaf-Witten theory [PDF]

open access: bronzeAdvances in Mathematics, 2019
In this work, for a finite group $G$ and a 4-cocycle $ \in Z^4(G, \mathbf{k}^\times)$, we compute explicitly the center of the monoidal 2-category $\operatorname{2Vec}_G^ $ of $ $-twisted $G$-graded 1-categories of finite dimensional $\mathbf{k}$-vector spaces.

Centers and homotopy centers in enriched monoidal categories [PDF]

open access: yesAdvances in Mathematics 230 (2012), 1811-1858, 2011
We consider a theory of centers and homotopy centers of monoids in monoidal categories which themselves are enriched in duoidal categories. Duoidal categories (introduced by Aguillar and Mahajan under the name 2-monoidal categories) are categories with ...

Categorial compositionality: a category theory explanation for the systematicity of human cognition. [PDF]

open access: yesPLoS Computational Biology, 2010
Classical and Connectionist theories of cognitive architecture seek to explain systematicity (i.e., the property of human cognition whereby cognitive capacity comes in groups of related behaviours) as a consequence of syntactically and functionally ...

Frobenius and the derived centers of algebraic theories [PDF]

open access: yesMath. Z. 285 (2017) 1181-1203, 2014
We show that the derived center of the category of simplicial algebras over every algebraic theory is homotopically discrete, with the abelian monoid of components isomorphic to the center of the category of discrete algebras. For example, in the case of

Functoriality of the center of an algebra [PDF]

open access: yesAdvances in Mathematics 285 (2015) 811-876, 2013
The notion of the center of an algebra over a field k has a far reaching generalization to algebras in monoidal categories. The center then lives in the monoidal center of the original category. This generalization plays an important role in the study of

On continuous 2-category symmetries and Yang-Mills theory

open access: yesJournal of High Energy Physics, 2022
We study a 4d gauge theory U(1) N−1 ⋊ S N obtained from a U(1) N−1 theory by gauging a 0-form symmetry S N . We show that this theory has a global continuous 2-category symmetry, whose structure is particularly rich for N > 2.

The sustainable semantic foundations of the traditional neighborhoods in the desert cities [PDF]

open access: yesInternational Journal of Human Capital in Urban Management, 2022
BACKGROUND AND OBJECTIVES: In cities with a hot and harsh climate, defining space and territory in a sustainable and environmentally manner in urban management and human capital is critical. Cultural values and climatic adaptation played a prominent role
