Alternative Dirichlet Priors for Estimating Entropy via a Power Sum Functional

Mathematics, 2021
Entropy is a functional of probability and is a measurement of information contained in a system; however, the practical problem of estimating entropy in applied settings remains a challenging and relevant problem. The Dirichlet prior is a popular choice

Numerical Analysis of Fourier Finite Volume Element Method for Dirichlet Boundary Optimal Control Problems Governed by Elliptic PDEs on Complex Connected Domains

Mathematics, 2022
In this research, we investigate an optimal control problem governed by elliptic PDEs with Dirichlet boundary conditions on complex connected domains, which can be utilized to model the cooling process of concrete dam pouring.

Smoothed Dirichlet Distribution

Journal of Statistical Theory and Applications (JSTA), 2023
When the cells are ordinal in the multinomial distribution, i.e., when cells have a natural ordering, guaranteeing that the borrowing information among neighboring cells makes sense conceptually.

Relations between Limit-Point and Dirichlet Properties of Second-Order Difference Operators

Advances in Difference Equations, 2007
We consider second-order difference expressions, with complex coefficients, of the form wn−1[−Δ(pn−1Δxn−1)+qnxn] acting on infinite sequences.

A Bayesian Approach to Linking a Survey and a Census via Small Areas

Stats, 2021
We predict the finite population proportion of a small area when individual-level data are available from a survey and more extensive household-level (not individual-level) data (covariates but not responses) are available from a census.

Quantum “violation” of Dirichlet boundary condition

Physics Letters B, 2017
Dirichlet boundary conditions have been widely used in general relativity. They seem at odds with the holographic property of gravity simply because a boundary configuration can be varying and dynamic instead of dying out as required by the conditions ...

Brief introduction to distributions and to Hörmander spaces Bp,k

Selecciones Matemáticas
Partial differential equations (PDE’s) are, we believe, little known in our country, especially at a medium-advanced level, in particular, their historical roots and methods developed in their evolution.

Interior Regularity Estimates for a Degenerate Elliptic Equation with Mixed Boundary Conditions

Axioms, 2018
The Marchaud fractional derivative can be obtained as a Dirichlet-to–Neumann map via an extension problem to the upper half space. In this paper we prove interior Schauder regularity estimates for a degenerate elliptic equation with mixed Dirichlet ...
