This paper proposes the continuous-time singular value decomposition (SVD) for the impulse response function, a special kind of Green’s functions, in order to find a set of singular functions and singular values so that the convolutions of such function with…

In this article, we study the Kolmogorov-Smirnov type goodness-of-fit test for the inhomogeneous Poisson process with the unknown translation parameter as multidimensional parameter. The basic hypothesis and the alternative are composite and carry to the inte…

In this article, by using a fixed point theorem, we study following fourth-order three-point BVP: where f ∈ C ([0,1]×[0,+∞),[0,+∞)) α ∈ [0,6) and . The main point to emphasize is that although the corresponding Green’s function is changing signs, by applying…

Consider the following system of coupled Korteweg-de Vries equations, where u , v ⊆ W 2,2 , 2≤ N ≤7 and λ i , β > 0, β denotes a real coupling parameter. Firstly, we prove the existence of the solutions of a coupled system of Korteweg-de Vries equations…

In this paper, we mainly study a diffusive Lotka-Volterra competition-advection system with lethal boundary conditions in a general heterogeneous environment. By using the basic theory of partial differential equations and some nonlinear analysis techniques,…

This paper selects the daily data of national oil prices from January 2, 2014 to February 28, 2019, establishes an ARMA (2, 0) model, and tests its residuals for ARCH effects. Finally, the TARCH (1, 1) model is determined to quantitatively analyze the volatil…

Let x and y be two positive real numbers with x < y . Consider a traveler, on the interval [0, y /2], departing from 0 and taking steps of length equal to x . Every time a step reaches an endpoint of the interval, the traveler rebounds off the endpoint in ord…

The spectral radius of a graph is the maximum eigenvalues of its adjacency matrix. In this paper, using the property of quotient graph, the sharp upper bounds for the spectral radii of some adhesive graphs are determined.

The purpose of this paper is to model ethical consumption behaviour based on price-dependent preferences. We motivate ethical consumption founded on the idea that ethical consumers compete for moral superiority relative to their peers by purchasing more expen…

In this paper, we propose new finite volume element schemes to numerically solve the improved Boussinesq equation with Stokes damping. The new schemes can inherit characteristic properties of the conservation of mass and the decrease of total energy from the…
