A factorization of regularity

open access: yesJournal of Pure and Applied Algebra, 2005
In any category, the kernel of a morphism \(f: X\to A\) is the class \(\ker(f)\) of parallel morphisms \((x, y): T\rightrightarrows X\) satisfying \(fx =fy\). A functor \(F: {\mathcal C}\to{\mathcal D}\) is said to preserve kernel inclusions whenever for any span (\(f: X\to A\), \(g: X\to B\)) in \({\mathcal C}\), if \(\ker(f)\subset\ker(g)\) then ...

Mild solutions to Love-type equations on R^2

open access: yesElectronic Journal of Differential Equations
In this article, we study a non-local Love problem on unbounded domains where the non-locality in the main equation is interpreted as a fractional Laplacian operator.

On a reaction-diffusion system associated with brain lactate kinetics

open access: yesElectronic Journal of Differential Equations, 2017
Our aim in this article is to study properties of a reaction-diffusion system which is related with brain lactate kinetics, when spatial diffusion is taken into account. In particular, we prove the existence and uniqueness of nonnegative solutions and

On regular graphs. II

open access: yesJournal of Combinatorial Theory, Series B, 1971
AbstractThis paper is a continuation of [1] and we shall use the same terminology. The main result of this part is the following: Suppose that the automorphism group of a connected graph of valency p + 1, p a prime, has a subgroup which acts as a regular permutation group on the set of s-arcs of the graph. Then s ≤ 7 and s ≠ 6.

The BKM criterion to the 3D double-diffusive magneto convection systems involving planar components

open access: yesMathematical Modelling and Analysis
In this paper, we investigate the BKM type blowup criterion applied to 3D double-diffusive magneto convection systems. Specifically, we demonstrate that a unique local strong solution does not experience blow-up at time T, given that ).

On regular and intra-regular poe-semigroups

open access: yesSemigroup Forum, 1984
This note follows a long series of papers of the same author on regular poe-semigroups [see e.g. ibid. 19, 111-121 (1980; Zbl 0434.06015); 23, 85-86 (1981; Zbl 0467.06010); 25, 213-222 (1982; Zbl 0499.06012); 28, 371-372 (1984; Zbl 0534.06006)]. The author establishes a characterization of le-semigroups which are intra-regular and of the intra-regular ...
