The new combinatorial identities of symmetric functions

In this paper, we provide some novel binomial convolution related to symmetric functions, as well as convolution sums without the binomial symbol. Moreover we give some new convolution sums of Bernoulli, Euler, and Genocchi numbers and polynomials with symmetric functions , by making use of the elementary methods including exponential generating functions. From these convolutions we deduce several new combinatorial identities for bivariate polynomials, and we establish several new identities related Bernoulli, Euler and Genocchi numbers and polynomials with certain bivariate polynomials such as bivariate Fibonacci, bivariate Lucas, bivariate balancing and bivariate balancing-Lucas polynomials.

Existence result for Kirchhoff elliptic system with variable parameters

The paper deals with the study of the existence result for a Kirchhoff elliptic system with additive right hand side and variable parameters by using the sub-super solutions method. Our study is the second result of our previous once in (Math. Methods Appl. Sci. 41 (2018), 5203-5210).

Existence and multiplicity of positive weak solutions for a new class of $(p; q)$-Laplacian systems

The paper is concerned with the existence of positive weak solutions for a new class of $\left( p,q\right) $-Laplacian elliptic systems in a bounded domain by means of the method of sub-super solutions. Particularly, we do not need any sign conditions for $γ\left( 0\right), g\left( 0\right), f\left( 0\right) $ and $h\left(0\right) $. Moreover, a multiplicity result is obtained when $γ\left(0\right)=g\left( 0\right)=f\left( 0\right)=h\left( 0\right)=0.$ Finally, we give some examples to verify our main results.
