We determine the full automorphism group of each member of three infinite families of connected cubic graphs which are snarks. A graph is said to be nearly hamiltonian if it has a cycle which contains all vertices but one. We prove, in particular, that fo... see more

The aim of this paper is to study r–generalized gamma functions of a particular form.Moreover, we define a new probability density function (p.d.f) involving these new generalized functions. Some basic functions associated with the p.d.f’s, such as moment... see more

Sufficient conditions for the existence of solutions of the periodic and anti-periodic boundary value problems for nonlinear functional difference equations are established, respectively.

In this paper, using the q^2 -Laplace transform early introduced by Abdi [1], we study q-Wave polynomials related with the q-difference operator ?q,x . We show in particular that they are linked to the q-little Jacobi polynomials p_n (x; a, ß | q^2 ).

Let X be a smooth genus g curve equipped with a simple morphism f: X -> C, where C is either the projective line or more generally any smooth curve whose gonality is computed by finitely many pencils. Here we apply a method developed by Aprodu to prove... see more

We study the Hilbert function and the Hilbert series of the vertex cover algebra A(G), where G is a Cohen-Macaulay bipartite graph.

The present note envisage to derive some new classes of multiple q-series transformations and reduction formulae. Special cases in terms ofthe known and new results are also derived.

We prove a generalization of Bernoulli's inequality and we apply this generalization to sharpen certain Weierstrass product inequalities

In this paper, we investigate the b-chromatic number of central graph, middle graph and total graph of star graph, denoted by C(K1,n), M(K1,n)  and  T(K1,n) respectively. We discuss the relationship between b-chromatic number with some other typ... see more

We give sufficient conditions to assure the existence of a monotone solution for a functional differential inclusions of second order with Caratheodory perturbation. No convexity condition is involved on the values of the right hand side in the constructi... see more

We prove that essentially alpha-hyponormal operators with zero area of the essential spectrum are essentially normal.
