Category of $A_{\infty}$-categories [PDF]

open access: yesHomology, Homotopy and Applications, 2003
An \(A_\infty\)-algebra is an algebra for Stasheff's associahedra (non-symmetric) operad on chain complexes. An \(A_\infty\)-category is a several object version of this, although the name might better be used for the unital case. There is a straightforward concept of \(A_\infty\)-functor; and the author here defines natural \(A_\infty ...

Quasi-hereditary twisted category algebras [PDF]

open access: yes, 2013
We give a sufficient criterion for when a twisted finite category algebra over a field is quasi-hereditary, in terms of the partially ordered set of L-classes in the morphism set of the category.

The Equivariant Cobordism Category

open access: yes, 2020
For a finite group $G$, we define an equivariant cobordism category $\mathcal{C}_d^G$. Objects of the category are $(d-1)$-dimensional closed smooth $G$-manifolds and morphisms are smooth $d$-dimensional equivariant cobordisms.

open access: yesIEEE Access, 2023
The problem of maximum inner product search (MIPS) is one of the most important components in machine learning systems. However, this problem does not care about diversity, although result diversification can improve user satisfaction.

Syntactic Monoids in a Category [PDF]

open access: yes, 2015
The syntactic monoid of a language is generalized to the level of a symmetric monoidal closed category D. This allows for a uniform treatment of several notions of syntactic algebras known in the literature, including the syntactic monoids of Rabin and ...
