Ambient Noise Data Processing to Obtain Group Velocity for Subsurface Structure Identification: Preliminary Research in Hululais Geothermal Field, Sumatra, Indonesia

open access: yesJGEET: Journal of Geoscience, Engineering, Environment and Technology, 2023
Hululais area lies in the pull-apart basins of the Ketaun Segment and Musi Segment fault as a part of the Sumatra Fault Zone (SFZ). The boundary normal faults of pull-apart basins play an important role as major discharge zones for geothermal fluid ...

Green function for hyperbolic media [PDF]

open access: yes, 2012
We revisit the problem of the electromagnetic Green function for homogeneous hyperbolic media, where longitudinal and transverse components of the dielectric permittivity tensor have different signs.

Existence of positive continuous weak solutions for some semilinear elliptic eigenvalue problems [PDF]

open access: yesOpuscula Mathematica, 2022
Let \(D\) be a bounded \(C^{1,1}\)-domain in \(\mathbb{R}^d\), \(d\geq 2\). The aim of this article is twofold. The first goal is to give a new characterization of the Kato class of functions \(K(D)\) that was defined by N.

Semiclassical Green Function in Mixed Spaces [PDF]

open access: yes, 1997
A explicit formula on semiclassical Green functions in mixed position and momentum spaces is given, which is based on Maslov's multi-dimensional semiclassical theory.

INCEPTION OF GREEN FUNCTION FOR THE THIRD-ORDER LINEAR DIFFERENTIAL EQUATION THAT IS INCONSISTENT WITH THE BOUNDARY PROBLEM CONDITIONS

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
Regarding the importance of teaching linear differential equations, it should be noted that every physical and technical phenomenon, when expressed in mathematical sciences, is a differential equation.

Phonon Green's function. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1991
The concepts of source and quantum action principle are used to produce the phonon Green's function appropriate for an initial phonon vacuum state. An application to the Mossbauer effect is presented.

On annealed elliptic Green function estimates [PDF]

open access: yes, 2014
We consider a random, uniformly elliptic coefficient field $a$ on the lattice $\mathbb{Z}^d$. The distribution $\langle \cdot \rangle$ of the coefficient field is assumed to be stationary.

Discrete Green's Functions

open access: yesJournal of Combinatorial Theory, Series A, 2000
The authors study discrete Green's functions and their relationship with discrete Laplace equations. They give different ways to construct such functions: Eigenfunctions or Cartesian product of graphs, among others.

The best constant of Sobolev inequality corresponding to anti-periodic boundary value problem

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
In this paper we establish the best constant of $\mathcal{L}^{p}$ Sobolev inequality for a function with anti-periodic boundary conditions. The best constant is expressed by $\mathcal{L}^q$ norm of $(M-1)$-th order Euler polynomial.

Four-point Green functions in the Schwinger Model [PDF]

open access: yes, 1998
The evaluation of the 4-point Green functions in the 1+1 Schwinger model is presented both in momentum and coordinate space representations. The crucial role in our calculations play two Ward identities: i) the standard one, and ii) the chiral one.
