Twisted Derivations in Algebraic Number Fields
Praveen Manju, Rajendra Kumar Sharma
Let be a commutative ring with unity and be an integral extension of . Assume that is an integral domain with quotient field and is…
-Derivations of Number Rings with Coding Theory Applications
Praveen Manju, Rajendra Kumar Sharma
In this article, we study -derivations of number rings by considering them as commutative unital -algebras. We begin by characterizing all -derivati…
The Exact Enumeration of -nomial and -nomial Multiples of the Product of Primitive Polynomials over GF(2)
Soniya Takshak, Rajendra Kumar Sharma
Linear feedback shift registers (LFSRs) are used to generate secret keys in stream cipher cryptosystems. There are different kinds of key-stream generators like filter generators,…
Inner and Outer Twisted Derivations of Cyclic Group Rings
Praveen Manju, Rajendra Kumar Sharma
In this article, we study twisted derivations of cyclic group rings. Let be a commutative ring with unity, be a finite cyclic group, and () be a pair of -algebra…
-primitive points on varieties over finite fields
Soniya Takshak, Giorgos Kapetanakis, Rajendra Kumar Sharma
Let be a positive divisor of and a rational function of degree sum over with some restrictions, where the degree sum of a rational function $f…
Inner and Outer Derivations of
Praveen Manju, Rajendra Kumar Sharma
Let be a field of characteristic or an odd rational prime . In this article, we give an explicit classification of all the inner and outer derivations of the gr…
