Signed Tropical Convexity [PDF]

open access: yes, 2020
We establish a new notion of tropical convexity for signed tropical numbers. We provide several equivalent descriptions involving balance relations and intersections of open halfspaces as well as the image of a union of polytopes over Puiseux series and ...

The moduli space of matroids [PDF]

open access: yes, 2018
In the first part of the paper, we clarify the connections between several algebraic objects appearing in matroid theory: both partial fields and hyperfields are fuzzy rings, fuzzy rings are tracts, and these relations are compatible with the respective ...

A bit of tropical geometry [PDF]

open access: yes, 2014
This friendly introduction to tropical geometry is meant to be accessible to first year students in mathematics. The topics discussed here are basic tropical algebra, tropical plane curves, some tropical intersections, and Viro's patchworking.

Witt rings of quadratically presentable fields [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2020
This paper introduces an approach to the axiomatic theory of quadratic forms based on {tmem{presentable}} partially ordered sets, that is partially ordered sets subject to additional conditions which amount to a strong form of local presentability.

Topological Grand Unification [PDF]

open access: yes, 2009
We propose a new grand unification scenario for ensuring proton stability and triplet-doublet Higgs mass splitting with the help of topological symmetry and dynamics.Comment: 9 pages, version to appear in ...

Hyperstructures in Lie-Santilli Admissibility and Iso-Theories

open access: yesRatio Mathematica, 2017
In the quiver of hyperstructures Professor R. M. Santilli, in early 90'es, tried to find algebraic structures in order to express his pioneer Lie-Santilli's Theory.

Derived Hyperstructures from Hyperconics

open access: yesMathematics, 2020
In this paper, we introduce generalized quadratic forms and hyperconics over quotient hyperfields as a generalization of the notion of conics on fields.

Extended Self-Dual Yang-Mills from the N=2 String [PDF]

open access: yes, 1998
We show that the physical degrees of freedom of the critical open string with N=2 superconformal symmetry on the worldsheet are described by a self-dual Yang-Mills field on a hyperspace parametrised by the coordinates of the target space R^{2,2} together

Hypercompositional Algebra, Computer Science and Geometry

open access: yesMathematics, 2020
The various branches of Mathematics are not separated between themselves. On the contrary, they interact and extend into each other’s sometimes seemingly different and unrelated areas and help them advance. In this sense, the Hypercompositional Algebra’s
