A Priori Estimate for the Complex Monge–Ampère Equation [PDF]
Peking Mathematical Journal, 2020 In this paper, we prove a Moser-Trudinger type inequality for pluri-subharmonic functions vanishing on the boundary. Our proof uses a descent gradient flow for the complex Monge-Ampere functional.

Bounded solutions for a class of Hamiltonian systems
Electronic Journal of Qualitative Theory of Differential Equations, 2018 We obtain solutions bounded for all $t \in (-\infty,\infty)$ of systems of ordinary differential equations as limits of the solutions of the corresponding Dirichlet problems on $(-L,L)$, with $L \to \infty$.

Cauchy–Dirichlet Problem to Semilinear Multi-Term Fractional Differential Equations
Fractal and Fractional, 2023 In this paper, we analyze the well-posedness of the Cauchy–Dirichlet problem to an integro-differential equation on a multidimensional domain Ω⊂Rn in the unknown u=u(x,t), Dtν0(ϱ0u)−Dtν1(ϱ1u)−L1u−∫0tK(t−s)L2u(x,s)ds=f(x,t)+g(u ...

A priori SNR estimation and noise estimation for speech enhancement [PDF]
EURASIP Journal on Advances in Signal Processing, 2016 A priori signal-to-noise ratio (SNR) estimation and noise estimation are important for speech enhancement. In this paper, a novel modified decision-directed (DD) a priori SNR estimation approach based on single-frequency entropy, named DDBSE, is proposed.

The Value of a Priori Information in Estimating a Financial Model [PDF]
The Journal of Finance, 1976 THIS PAPER REPORTS our initial efforts to use an explicitly Bayesian approach in estimating the asset demands of mutual savings banks and savings and loan associations. This is a part of a larger effort to construct and estimate a model of financial markets using flow of funds data.

Quasi-A Priori Truncation Error Estimation in the DGSEM [PDF]
Journal of Scientific Computing, 2014 In this paper we show how to accurately perform a quasi-a priori estimation of the truncation error of steady-state solutions computed by a discontinuous Galerkin spectral element method. We estimate the spatial truncation error using the ?-estimation procedure.

The Surrogate Matrix Methodology: A Priori Error Estimation [PDF]
SIAM Journal on Scientific Computing, 2019 We give the first mathematically rigorous analysis of an emerging approach to finite element analysis (see, e.g., Bauer et al. [Appl. Numer. Math., 2017]), which we hereby refer to as the surrogate matrix methodology. This methodology is based on the piece-wise smooth approximation of the matrices involved in a standard finite element discretization ...

Existence of positive solutions of elliptic equations with Hardy term
Electronic Journal of Qualitative Theory of Differential EquationsThis paper is devoted to studying the existence of positive solutions of the problem: \begin{equation} \begin{cases}\label{0.1}\tag{$\ast$} -\Delta u=\frac{u^{p}}{|x|^{a}}+h(x,u,\nabla u), & \mbox{in} \ \Omega,\\ u=0, & \mbox{on}\ \partial\Omega,\\ \end{
