Hyperbolic functions obtained from k-Jacobsthal sequences

Asian-European Journal of Mathematics, 2022
In this paper, an expansion of the classical hyperbolic functions is presented and studied. Also, many features of the [Formula: see text]-Jacobsthal hyperbolic functions are given. Finally, we introduced some graph and curved surfaces related to the [Formula: see text]-Jacobsthal hyperbolic functions.

The (s, t) Jacobsthal and (s, t) Jacobsthal-Lucas Matrix Sequences.

Ars Comb., 2013
In this study, we first define new sequences named (s, t)-Jacobsthal and (s, t) Jacobsthal-Lucas sequences. After that, by using these sequences, we establish (s,t)-Jacobsthal and (s, t) Jacobsthal-Lucas matrix sequences. Finally we present some important relationships between these matrix sequences.

The (s, t)-Generalized Jacobsthal Matrix Sequences

2016
In this study, we consider sequences named (s, t)-Jacobsthal, (s, t)-Jacobsthal–Lucas and defined generalized (s, t)-Jacobsthal integer sequences. After that, by using these sequences, we define generalized (s, t)-Jacobsthal matrix sequence in which it generalizes (s, t)-Jacobsthal matrix sequence, (s, t)-Jacobsthal–Lucas matrix sequence at the same ...

THE JACOBSTHAL SEQUENCES IN FINITE GROUPS

2016
In this paper, we study the generalized order-k Jacobsthal sequences modulo m for k >= 2 and the generalized order-k Jacobsthal-Padovan sequence modulo m for k >= 3. Also, we define the generalized order-k Jacobsthal orbit of a k-generator group for k >= 2 and the generalized order-k Jacobsthal-Padovan orbit a k-generator group for k >= 3. Furthermore,
