Going Beyond the Data as the Patching (Sheaving) of Local Knowledge

open access: yesFrontiers in Psychology, 2018
Consistently predicting outcomes in novel situations is colloquially called “going beyond the data,” or “generalization.” Going beyond the data features in spatial and non-spatial cognition, raising the question of whether such features have a common ...

A short history of algebraic statistics [PDF]

open access: yes, 2008
In algebraic statistics, computational techniques from algebraic geometry become tools to address statistical problems. This, in turn, may prompt research in algebraic geometry. The basic ideas at the core of algebraic statistics will be presented. In

On a notion of entropy in coarse geometry

open access: yesTopological Algebra and its Applications, 2019
The notion of entropy appears in many branches of mathematics. In each setting (e.g., probability spaces, sets, topological spaces) entropy is a non-negative real-valued function measuring the randomness and disorder that a self-morphism creates. In this

Applications of the Topological Data Analysis in Real Life

open access: yesWSEAS Transactions on Mathematics, 2022
Statistical topology inference is a branch of algebraic topology that analyzes the geometric structure's global topological properties underlying a point cloud dataset.

Algebraic entropy for algebraic maps [PDF]

open access: yes, 2015
We propose an extension of the concept of algebraic entropy, as introduced by Bellon and Viallet for rational maps, to algebraic maps (or correspondences) of a certain kind. The corresponding entropy is an index of the complexity of the map.

On the geometry and topology of Cayley condition in Poncelet porism for triangles [PDF]

open access: yesDifferential geometry and its applications
This paper investigates the differential-geometric and topological properties of the Cayley condition in Poncelet porism for triangles, defined as the locus of pairs of non-degenerate conics that admit a Poncelet triangle.

Topology of nonarchimedean analytic spaces and relations to complex algebraic geometry [PDF]

open access: yes, 2013
This note surveys basic topological properties of nonarchimedean analytic spaces, in the sense of Berkovich, including the recent tameness results of Hrushovski and Loeser.

Gauge-invariant projector calculus for quantum state geometry and applications to observables in crystals [PDF]

open access: yes
The importance of simple geometrical invariants, such as the Berry curvature and quantum metric, constructed from the Bloch states of a crystal has become well-established over four decades of research.

Topological Multi-groups and Multi-fields [PDF]

open access: yes, 2009
Topological groups, particularly, Lie groups are very important in differential geometry, analytic mechanics and theoretical physics. Applying Smarandache multi-spaces, topological spaces, particularly, manifolds and groups were generalized to ...
