Commutative Medial Near Ring

open access: yesRatio Mathematica, 2023
We deliberate a substructure of a near ring called mediality so as to create a new platform, on which many of the properties like commutativity, regular, idempotent and zero symmetric are applied with.

Regular Partitions of Regular Graphs [PDF]

open access: yesCanadian Mathematical Bulletin, 1978
In the study of the combinatorial structure of edge-graphs of convex polytopes one may ask whether a given graph possesses a partition consisting of certain kinds of subgraphs.In this paper we describe some special partitions of 3-valent and 4-valent graphs.

Hadamard regularization [PDF]

open access: yesJournal of Mathematical Physics, 2000
Motivated by the problem of the dynamics of point-particles in high post-Newtonian (e.g., 3PN) approximations of general relativity, we consider a certain class of functions which are smooth except at some isolated points around which they admit a power-like singular expansion.

Piecewise-regular maps [PDF]

open access: yes, 2017
Let V, W be real algebraic varieties (that is, up to isomorphism, real algebraic sets), and let X be a subset of V. A map f from X into W is said to be regular if it can be extended to a regular map defined on some Zariski locally closed subvariety of V ...

Families of nested completely regular codes and distance-regular graphs [PDF]

open access: yes, 2014
In this paper infinite families of linear binary nested completely regular codes are constructed. They have covering radius $\rho$ equal to $3$ or $4$, and are $1/2^i$-th parts, for $i\in\{1,\ldots,u\}$ of binary (respectively, extended binary) Hamming ...

Directional Regularity and Metric Regularity

open access: yesSIAM Journal on Optimization, 2007
For general constraint systems in Banach spaces, we present the directional stability theorem based on the appropriate generalization of the directional regularity condition, suggested earlier in [A. V. Arutyunov and A. F. Izmailov, Math. Oper. Res., 31 (2006), pp. 526-543].

Regular S-Brane Backgrounds [PDF]

open access: yes, 2004
We construct time-dependent S-brane solutions to the supergravity field equations in various dimensions which (unlike most such geometries) do not contain curvature singularities.

Regular Homomorphisms and Regular Maps

open access: yesEuropean Journal of Combinatorics, 2002
The authors study regular automorphisms of oriented maps. Their main concern is the problem of lifting and projecting map automorphisms. Regular homomorphisms of oriented maps essentially arise from a factorization by a subgroup of automorphisms. In this paper, this kind of map automorphisms is studied in detail.

Building Regular Registers with Rational Malicious Servers and Anonymous Clients [PDF]

open access: yes, 2017
The paper addresses the problem of emulating a regular register in a synchronous distributed system where clients invoking $$\mathsf{read}()$$ and $$\mathsf{write}()$$ operations are anonymous while server processes maintaining the state of the register ...
