Open AccessGlobal dynamics of a two-species clustering model with Lotka–Volterra competition
This paper is concerned with the global dynamics of a two-species Grindrod clustering model with Lotka–Volterra competition. The model takes the advective flux to depend directly upon local population densitie...

Open AccessPrescribing Gaussian curvature on surfaces with conical singularities and geodesic boundary
We study conformal metrics with prescribed Gaussian curvature on surfaces with conical singularities and geodesic boundary in supercritical regimes. Exploiting a variational argument, we derive a general exist...

Open AccessImproved stability criteria for generalized neural networks with time-varying delay by auxiliary function-based integral inequality
This paper is mainly concerned with improved stability criteria for generalized neural networks (GNNs) with time-varying delay by delay-partitioning approach. A newly augmented Lyapunov-Krasovskii functional (...

Optimization Methods for Mixed Integer Weakly Concave Programming Problems
In this paper, we consider a class of mixed integer weakly concave programming problems (MIWCPP) consisting of minimizing a difference of a quadratic function and a convex function. A new necessary global opti...

Reflected Symmetric α-Stable Processes and Regional Fractional Laplacian
In this paper we investigate the reflected symmetric α-stable processes and their generators. We show that the generators are regional fractional Laplacians on the closed region. In the case of 1≤α<2 their existe...
