A combinatorial commutativity property for rings [PDF]
We study commutativity in rings R with the property that for a fixed positive integer n, xS = Sx for all x ∈ R and all n‐subsets S of R.

On the commutative properties of boundary integral operators [PDF]
A discussion of the interior Dirichlet and Neumann problems of classical potential theory can be given in terms of the symmeterisers of certain related integral operators. Recent developments in the theory and application of integral equations of the first kind have made this approach towards the solution of boundary value problems a more attractive ...

On the Commutation Properties of Finite Convolution and Differential Operators I: Commutation. [PDF]
The commutation relation $KL = LK$ between finite convolution integral operator $K$ and differential operator $L$ has implications for spectral properties of $K$. We characterize all operators $K$ admitting this commutation relation. Our analysis places no symmetry constraints on the kernel of $K$ extending the well-known results of Morrison for real ...

Hypercyclicity Properties of Commutator Maps [PDF]
We investigate the hypercyclic properties of commutator maps acting on separable ideals of operators. As the main result we prove the commutator map induced by scalar multiples of the backward shift operator fails to be hypercyclic on the space of compact operators on $\ell^2$. We also establish some necessary conditions which identify large classes of

On idempotent stable range 1 matrices
We characterize the idempotent stable range 1, 2 × 2 matrices over commutative rings and in particular the integral matrices with this property. Several special cases and examples complete the subject.

The universal property of commutative algebras' internal crossed modules
In this work, we identify subobjects and ideals in the category of internal crossed modules, which provide a deeper understanding of the structure of these objects.

Properties of the combinations of commutative idempotents [PDF]
AbstractThis paper deals with idempotent operators (i.e., P2=P) and n-potent operators (i.e., Pn=P). We characterize the invertibility, the group invertibility and idempotency of the linear combinations of idempotent operators (or n-potent operators) under certain commutativity property imposed on them.

Computation of eccentric topological indices of zero-divisor graphs based on their edges
The topological index of a graph gives its topological property that remains invariant up to graph automorphism. The topological indices which are based on the eccentricity of a chemical graph are molecular descriptors that remain constant in the whole ...

The Ideal Intersection Property for Groupoid Graded Rings [PDF]
We show that if a groupoid graded ring has a certain nonzero ideal property, then the commutant of the center of the principal component of the ring has the ideal intersection property, that is it intersects nontrivially every nonzero ideal of the ring ...
