Well-Posedness for Fractional $(p,q)$-Difference Equations Initial Value Problem

In this paper, we investigate a class of the fractional $(p,q)$-difference initial value problem with the fractional $(p,q)$-integral boundary conditions with the aid of the method of successive approximations(Picard method) and fractional $(p,q)$-Gronwall inequality, obtaining sufficient conditions for the existence, uniqueness and continuous dependence results of solutions.

On the (p,q)$(p,q)$-type strong law of large numbers for sequences of independent random variables

Li, Qi, and Rosalsky (Trans. Amer. Math. Soc., 368 (2016), no. 1, 539–561) introduced a refinement of the Marcinkiewicz–Zygmund strong law of large numbers (SLLN), the so-called $(p,q)$-type SLLN, where and $q>0$. They obtained sets of necessary and sufficient conditions for this new type SLLN for two cases: , $q>p$, and . Results for the case where and remain open problems. This paper gives a complete solution to these problems. We consider random variables taking values in a real separable Banach space $\mathbf{B}$, but the results are new even when $\mathbf{B}$ is the real line. Furthermore, the conditions for a sequence of random variables $\left\{X_n,n\ge 1\right\}$ satisfying the $(p,q)$-type SLLN are shown to provide an exact characterization of stable type p Banach spaces.     

Solvability and Stability for Singular Fractional (p,q)-difference Equation

In this paper, we initiate the solvability and stability for a class of singular fractional $(p,q)$-difference equations. First, we obtain an existence theorem of solution for the fractional $(p,q)$-difference equation. Then, by using a fractional $(p,q)$-Gronwall inequality, some stability criteria of solution are established, which also implies the uniqueness of solution.

Fixed Point Theorems for (p,q)-Quasi-Contraction Mappings in Cone Metric Spaces

In this work, the authors introduce the concept of $(p,q)$-quasi-contraction mapping in a cone metric space. We prove the existence and uniqueness of a fixed point for a $(p,q)$-quasi-contraction mapping in a complete cone metric space. The results of this paper generalize and unify further fixed point theorems for quasi-contraction, convex contraction mappings and two-sided convex contraction of order $2$.

The present paper studies and investigates a class of Mittag-Leffler type multivariable functions.

The systems discussed in this paper and the method used extend and complement some of the previous work.     

MA$(q)$模型的经验似然推断

In this article we study the empirical likelihood inference for MA（q） model. We propose the moment restrictions, by which we get the empirical likelihood estimator of the model parameter, and we also propose an empirical log-likelihood ratio based on this estimator. Our result shows that the EL estimator is asymptotically normal, and the empirical log-likelihood ratio is proved to be asymptotical standard chi-square distribution.

Variational formulation for nonlinear impulsive fractional differential equations with (p,q)-Laplacian operator

In this paper, we focus on a class of generalized (p, q)-Laplacian-type impulsive fractional differential equation for 1 < p≤q < ∞, with a nonlinearity f containing fractional derivatives ${}_0{D}_t^{\alpha }u$ and ${}_0{D}_t^{\beta }u$ simultaneously and being imposed on mild assumptions contrasting with previous works. The underlying idea is based on the Mountain pass theorem and the iterative technique to obtain the existence of nontrivial solutions for our equation. Our work extends and supplements some existing results.

In this paper, the following $p(x)$-Laplacian equation: $$Δ_{p(x)}u+V(x)|u|^{p(x)-2}u=Q(x)f(x,u), \ \ x∈\mathbb{R}^N,$$ is studied. By applying an extension of Clark's theorem, the existence of infinitely many solutions as well as the structure of the set of critical points near the origin are obtained.
