Nullity and Loop Complementation for Delta-Matroids [PDF]

open access: yes, 2012
We show that the symmetric difference distance measure for set systems, and more specifically for delta-matroids, corresponds to the notion of nullity for symmetric and skew-symmetric matrices. In particular, as graphs (i.e., symmetric matrices over GF(2)

About contract conversion in Serbian law with special reference to the court conversion [PDF]

open access: yesAnali Pravnog Fakulteta u Beogradu, 2020
In theoretical works of domestic authors the institute of conversion seems to be unjustifiably neglected. Nevertheless, this institute raises a number of questions that our theory and practice do not answer uniquely.

On a type of almost Kenmotsu manifolds with nullity distributions

open access: yesArab Journal of Mathematical Sciences, 2017
The object of the present paper is to characterize Weyl semisymmetric almost Kenmotsu manifolds with its characteristic vector field ξ belonging to the (k,μ)′-nullity distribution and (k,μ)-nullity distribution respectively.

Fractional Perfect b-Matching Polytopes. I: General Theory [PDF]

open access: yes, 2013
The fractional perfect b-matching polytope of an undirected graph G is the polytope of all assignments of nonnegative real numbers to the edges of G such that the sum of the numbers over all edges incident to any vertex v is a prescribed nonnegative ...

A geometric study of marginally trapped surfaces in space forms and Robertson-Walker spacetimes -- an overview

open access: yes, 2020
A marginally trapped surface in a spacetime is a Riemannian surface whose mean curvature vector is lightlike at every point. In this paper we give an up-to-date overview of the differential geometric study of these surfaces in Minkowski, de Sitter, anti ...

Theoretical and Practical Aspects Regarding the Nulity of Commercial Companies [PDF]

open access: yesTheoretical and Applied Economics, 2009
The absence of a Romanian legal definition of the concept of nullity of commercial companies arouses a lot of questions. The delimitation of this concept is very important for a correct establishment of its field of application.

Mental illness and nullity of marriage: Indian perspective

open access: yesIndian Journal of Psychological Medicine, 2015
Marriage is a social institution that formalizes and stabilizes the union between a man and wife. At times, either of the parties undergoing the contract of marriage may ask it be declared null and void.

open access: yesForum Juridic, 2021
By using as an example the recent developments in the area of priority rules for vaccination of the population, this paper looks at the way the wording of the rules could be used against their intended meaning. Also, it is debated the ethics and legality

Classification of the nullity for the second order discrete nonlocal problems

open access: yesLietuvos Matematikos Rinkinys, 2014
In this paper we investigate the nullity of second order discrete problem with two nonlocal conditions. The classification of nullity with respect to rows and columns of discrete problem matrix is presented. The research was partially supported by the

Sewing cells in almost cosymplectic and almost Kenmotsu geometry [PDF]

open access: yes, 2012
For a finite family of 3-dimensional almost contact metric manifolds with closed the structure form $\eta$ is described a construction of an almost contact metric manifold, where the members of the family are building blocks - cells.
