The weak Dirichlet problem.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1984
Let S(U) denote the cone of all P-bounded real continuous functions on a P-harmonic space \((X,^*H)\) which are superharmonic on the open subset \(U\subseteq X\). The authors have previously shown [Invent. Math. 29, 83- 110 (1975; Zbl 0308.31011)] that \(S(U)\) is implying that the weak Dirichlet problem is solvable: For any compact subset \(K\subseteq

Bipolynomial fractional Dirichlet-Laplace problem

open access: yesElectronic Journal of Differential Equations, 2019
In the article, we derive the existence of solutions for a nonlinear non-autonomous partial elliptic system on an open bounded domain with Dirichlet boundary conditions.

Dirichlet problem for quasi-linear elliptic equations

open access: yesElectronic Journal of Differential Equations, 2002
We study the Dirichlet Problem associated to the quasilinear elliptic problem $$ -sum_{i=1}^{n}frac{partial }{partial x_i}mathcal{A}_i(x,u(x), abla u(x))+mathcal{B}(x,u(x),abla u(x))=0.

Generative Supervised Classification Using Dirichlet Process Priors. [PDF]

open access: yes, 2010
Choosing the appropriate parameter prior distributions associated to a given Bayesian model is a challenging problem. Conjugate priors can be selected for simplicity motivations.

Sampling from Dirichlet process mixture models with unknown concentration parameter: mixing issues in large data implementations [PDF]

open access: yes, 2014
We consider the question of Markov chain Monte Carlo sampling from a general stick-breaking Dirichlet process mixture model, with concentration parameter (Formula presented.).

Recovering the shape of an equilateral quantum tree with the Dirichlet conditions at the pendant vertices [PDF]

open access: yesOpuscula Mathematica
We consider two spectral problems on an equilateral rooted tree with the standard (continuity and Kirchhoff's type) conditions at the interior vertices (except of the root if it is interior) and Dirichlet conditions at the pendant vertices (except of the

A nonparametric predictive alternative to the Imprecise Dirichlet Model: the case of a known number of categories [PDF]

open access: yes, 2006
Nonparametric Predictive Inference (NPI) is a general methodology to learn from data in the absence of prior knowledge and without adding unjustified assumptions.

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

open access: yesAxioms, 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 ...

Three spectra problem for Stieltjes string equation and Neumann conditions

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2019
Spectral problems are considered which appear in description of small transversal vibrations of Stieltjes strings. It is shown that the eigenvalues of the Neumann-Neumann problem, i.e.
