Existence and uniqueness of solutions for fractional stochastic delay differential equations
Xi'an Gongcheng Daxue xuebao, 2021 The existence and uniqueness of solutions for a class fractional stochastic delay differential equations dx(t)=b(x(t), x(t-τ), t)dt+σ1(x(t), x(t-τ), t)dB(t)+σ2(x(t), x(t-τ), t)(dt)α of order α∈(0, 1) were studied.

Mathematics in Applied Sciences and Engineering, 2022 In this paper, we study a toxin-mediated size-structured population model with nonlinear reproduction, growth, and mortality rates. By using the characteristic method and the contraction mapping argument, we establish the existence-uniqueness of ...

Continuous-Time Modelling with Spatial Dependence [PDF]
SSRN Electronic Journal, 2011 (Spatial) panel data are routinely modeled in discrete time (DT). However, compelling arguments exist for continuous‐time (CT) modeling of (spatial) panel data. Particularly, most social processes evolve in CT, so that statistical analysis in DT is an oversimplification, gives an incomplete representation of reality, and may lead to misinterpretation ...

Solutions of fractional nabla difference equations - existence and uniqueness [PDF]
Opuscula Mathematica, 2016 In this article, we discuss existence, uniqueness and dependency of solutions of nonlinear fractional nabla difference equations in a Banach space equipped with a suitable norm, using the contractive mapping approach. As an application of the established

Qualitative results in thermoelasticity of type III for dipolar bodies
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 In our study we formulated the mixed initial boundary value problem corresponding to the thermoelasticity of type III for bodies with dipolar structure. In main section we approached four qualitative results regarding the solutions for this problem.

Continuous dependence results for set-valued measure differential problems
Electronic Journal of Qualitative Theory of Differential Equations, 2015 We discuss existence and continuous dependence properties of solutions set of measure differential inclusions \begin{equation}\label{(1)} \begin{split} dx(t)& \in G(t, x(t)) d\mu(t),\\ x(0)& = x_0. \end{split} \end{equation} where $G \colon [0,1] \times \
