FORMATION OF MODERN MATHEMATICAL APPROACH TO SOLVING PROBLEMS OF PHYSICS

open access: yesФізико-математична освіта, 2022
Formulation of the problem. Precision studies of the Higgs boson, supersymmetric particles, the magnetic moment of the muon, electric dipole moment of the electron, flavor anomalies demonstrate the deviation beyond Standard Model. They are connected with

Space Tessellations. Polyhedral Sculpting

open access: yesSymmetry: Art and Science | 12th SIS-Symmetry Congress, 2022
At the Institute for Art and Design, a subunit of the Department of Architecture at TU Wien, every year, a non-mandatory artistic project is organized, open for Master Students (5 ECTS points). I will report on the development and the outcomes of this assignment, a research and de- sign project in the realm of sculpting based on polyhedral aggregations,

Three-Dimension Random Aggregate Generation of Numerical Concrete Model

open access: yesMATEC Web of Conferences, 2018
The aggregate generation of concrete is one of the important problems in concrete mesoscopic mechanics. Firstly, the mesoscopic numerical model with spherical aggregates is obtained by the method of excluding the occupied space, and fully-graded concrete

Lower and upper bounds for nef cones [PDF]

open access: yes, 2011
The nef cone of a projective variety Y is an important and often elusive invariant. In this paper we construct two polyhedral lower bounds and one polyhedral upper bound for the nef cone of Y using an embedding of Y into a toric variety. The lower bounds

Topological classification of the hyperspaces of polyhedral convex sets in normed spaces [PDF]

open access: yesМатематичні Студії, 2013
We prove that, for a normed space $X$ of dimension $dim(X)ge2$ the space $PConv_H(X)$ of non-empty polyhedral convexsubsets of $X$ endowed with the Hausdorff metric ishomeomorphic to the topological sum ${0}oplus |X^*|imes(IRoplus (IRimesarIR_+)oplus ...

Recursively-regular subdivisions and applications

open access: yesJournal of Computational Geometry, 2016
We generalize regular subdivisions (polyhedral complexes resulting from the projection of the lower faces of a polyhedron) introducing the class of recursively-regular subdivisions.

Cosmic Topology of Polyhedral Double-Action Manifolds

open access: yes, 2012
A special class of non-trivial topologies of the spherical space S^3 is investigated with respect to their cosmic microwave background (CMB) anisotropies.

Boolean hypercubes and the structure of vector spaces

open access: yesJournal of Mathematical Sciences and Modelling, 2018
The present study pretends to describe an alternative way to look at Vector Spaces as a scaffold to produce a meaningful new theoretical structure to be used in both classical and quantum QSPR.
