Color and Timbre Gestures: An Approach with Bicategories and Bigroupoids

open access: yesMathematics, 2022
White light can be decomposed into different colors, and a complex sound wave can be decomposed into its partials. While the physics behind transverse and longitudinal waves is quite different and several theories have been developed to investigate the ...

Category theory : definitions and examples [PDF]

open access: yes, 1990
Category theory was invented as an abstract language for describing certain structures and constructions which repeatedly occur in many branches of mathematics, such as topology, algebra, and logic.

The Structure and Organizations of ICHD-3 Differential Diagnoses through DiffNet: A Pilot Study

open access: yesDiagnostics, 2022
Differential diagnosis is fundamental to medicine. Using DiffNet, a differential diagnosis generator, as a model, we studied the structure and organization of how collections of diagnoses (i.e., sets of diagnoses) are related in the ICHD3.

Rigidification of algebras over multi-sorted theories

open access: yes, 2009
We define the notion of a multi-sorted algebraic theory, which is a generalization of an algebraic theory in which the objects are of different "sorts." We prove a rigidification result for simplicial algebras over these theories, showing that there is a

Categorical representation learning and RG flow operators for algorithmic classifiers

open access: yesMachine Learning: Science and Technology, 2023
Following the earlier formalism of the categorical representation learning, we discuss the construction of the ‘RG-flow-based categorifier’. Borrowing ideas from the theory of renormalization group (RG) flows in quantum field theory, holographic duality,

On the (co)homology theory of index category

open access: yesJournal of the Egyptian Mathematical Society, 2011
In the present work the different types of regular index categories are given. The related cohomology groups of some of these categories are studied. We give some properties of index category related with monoid and algebra over it.

Derived categories of NDG categories [PDF]

open access: yesarXiv, 2020
We study $N$-differential graded ($NDG$) categories and their the derived categories. First, we introduce $N$-differential modules over an $NDG$ category $\mathcal{A}$. Then we show that the category $\mathsf{C}_{Ndg}(\mathcal{A})$ of $N$-differential $\mathcal{A}$-modules is a Frobenius category, and that its homotopy category $\mathsf{K}_{Ndg ...

Diagrammatic category theory

open access: yes, 2023
In category theory, the use of string diagrams is well known to aid in the intuitive understanding of certain concepts, particularly when dealing with adjunctions and monoidal categories.

Fundamentals of soft category theory

open access: yesBulletin of Computational Applied Mathematics, 2018
The soft category theory offers a way to study soft theories developed so far more generally. The main purpose of this paper is to introduce the basic algebraic operations in soft categories, and for that we introduce some algebraic operations, like ...
