SYMMETRIC BI-DERIVATIONS IN ALMOST DISTRIBUTIVE LATTICES
In this paper, we introduce the concept of symmetric bi-derivation in an Almost Distributive Lattice (ADL) and derive some important properties of symmetric bi-derivations in ADLs.
CUBIC GENERALIZED BI-IDEALS IN SEMIGROUPS
In this paper, the concept of a cubic generalized bi-ideal in a semigroup is introduced, which is a generalization of the concept of a fuzzy generalized bi-ideal and interval-valued fuzzy generalized bi-ideal. Using this...
RIGHT DERIVATION OF ORDERED Γ-SEMIRINGS
In this paper, we introduce the concept of a right derivation of ordered Γ-semirings, we study some of the properties of right derivations of ordered Γ-semirings and we prove that if d is a non-zero right derivation of a...
APPLICATIONS OF SADDLE-POINT DETERMINANTS
For a given square matrix A ∈ Mn(R) and the vector e ∈ (R)^n of ones denote by (A, e) the matrix A e e^T 0 This is often called the saddle point matrix and it plays a significant role in several branches of m...
COMMUTATIVITY OF PRIME RINGS WITH SYMMETRIC BIDERIVATIONS
The present paper shows some results on the commutativity of R: Let R be a prime ring and for any nonzero ideal I of R, if R admits a biderivation B such that it satisfies any one of the following properties (i) B([x, y]...
