Permutation polynomials from the trace functions
Sartaj Ul Hasan, Ramandeep Kaur, Hridesh Kumar
We study necessary and sufficient conditions on for several classes of polynomials of the form to be permutation polynomials over finite…
Four new classes of permutation trinomials and their compositional inverses
Sartaj Ul Hasan, Ramandeep Kaur, Hridesh Kumar
We construct four new classes of permutation trinomials over the cubic extension of a finite field with even characteristic. Additionally, we explicitly provide the compositional i…
Some new results on permutation trinomials over finite fields with even characteristic
Kirpa Garg, Sartaj Ul Hasan, Chandan Kumar Vishwakarma
The construction of permutation trinomials of the form over $\F_{2^{2m}}$, where are positive integers, is an active are…
Local permutation polynomials and their companions
Sartaj Ul Hasan, Hridesh Kumar
Gutierrez and Urroz (2023) have proposed a family of local permutation polynomials over finite fields of arbitrary characteristic based on a class of symmetric subgroups without fi…
Some new classes of permutation polynomials and their compositional inverses
Sartaj Ul Hasan, Ramandeep Kaur
We focus on the permutation polynomials of the form $L(X)+\Tr_{m}^{3m}(X)^{s}$ over $\F_{q^3}$, where $\F_q$ is the finite field with elements, is a prime number, i…
The binary Gold function and its c-boomerang connectivity table
Sartaj Ul Hasan, Mohit Pal, Pantelimon Stanica
Here, we give a complete description of the c-Boomerang Connectivity Table for the Gold function over finite fields of even characteristic, by using double Weil sums. In the proces…
Dembowski-Ostrom polynomials and Dickson polynomials
Sartaj Ul Hasan, Mohit Pal
We give a complete classification of Dembowski-Ostrom polynomials from the composition of Dickson polynomials of arbitrary kind and monomials over finite fields. Moreover, by using…
Dembowski-Ostrom polynomials and reversed Dickson polynomials
Neranga Fernando, Sartaj Ul Hasan, Mohit Pal
We discuss the problem of classifying Dembowski-Ostrom polynomials from the composition of reversed Dickson polynomials of arbitrary kind and monomials over finite fields of odd ch…
Dembowski-Ostram polynomials and reversed Dickson polynomials
Neranga Fernando
We give a complete classification of Dembowski-Ostram polynomials from reversed Dickson polynomials in odd characteristic.
