We present a comparison result to discuss the periodic boundary value problem for neutral differential equation with piecewise constant delay.

In this paper we introduce h(x)-B-Tribonacci and h(x)-B-Tri Lucas polynomials. We also obtain the identities for these polynomials.

In this paper some identities of (k, j) sup(th) order partial derivatives of B-q bonacci and B-q Lucas polynomials with respect to x and y are introduced.

In this paper q-th order linear recurrence relation is defined. This new sequence is an extension of Fibonacci sequence in such a way that the coefficients of the terms on the right hand side of its recurrence relation, ...

In this paper we discuss the existence of a solution of a first order neutral differential equation with piecewise constant argument. We extend the method of Chaplygin's sequence to obtain two sided bounds for the solution. ...

In this paper we obtain the Lie invariance condition for second order partial differential equations. This condition is used to obtain the determining equations of the 1-dimensional wave equation with constant speed. The ...
