A conditions of solvability of the Goursat problem in quadratures for the two-dimensional system of high order

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
In this paper we consider the Goursat problem for the two-dimensional system of high order. The purpose is to find sufficient conditions of solvability of the considered problem in quadratures.

On the Goursat problem for a second order equation [PDF]

open access: yesElectronic Journal of Differential Equations, 2002
We consider the Goursat problem for second order operators and show existence and uniqueness of smooth solutions. We prove one of the results of Hasegawa (J. Math. Soc. Japan 50 (1998), no. 3, 639--662) by the energy method.

Generalized solutions to a non-Lipschitz Goursat problem [PDF]

open access: yesDifferential Equations & Applications, 2009
In this paper we investigate solutions to the semi-linear wave equation in canonical form with non Lipschitz non-linearity and distributions or other generalized functions as data. To give a meaning to the Goursat problem with irregular data, we replace it by a biparametric family of problems.

Lightweight Curvature Estimation on Point Clouds with Randomized Corrected Curvature Measures

open access: yesComputer Graphics Forum, Volume 42, Issue 5, August 2023., 2023
Abstract The estimation of differential quantities on oriented point cloud is a classical step for many geometry processing tasks in computer graphics and vision. Even if many solutions exist to estimate such quantities, they usually fail at satisfying both a stable estimation with theoretical guarantee, and the efficiency of the associated algorithm ...

Monodromy of four‐dimensional irreducible compatible systems of Q$\mathbb {Q}$

open access: yesBulletin of the London Mathematical Society, Volume 55, Issue 4, Page 1773-1790, August 2023., 2023
Abstract Let F$F$ be a totally real field and n⩽4$n\leqslant 4$ a natural number. We study the monodromy groups of any n$n$‐dimensional strictly compatible system {ρλ}λ$\lbrace \rho _\lambda \rbrace _\lambda$ of λ$\lambda$‐adic representations of F$F$ with distinct Hodge–Tate numbers such that ρλ0$\rho _{\lambda _0}$ is irreducible for some λ0$\lambda ...

Soil Deformation around a Cylindrical Cavity under Drained Conditions: Theoretical Analysis

open access: yesAdvances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
This paper proposes analytical solutions to the soil deformation around a cylindrical cavity under drained conditions. Analytical procedures are used to predict the degree of interaction between cavities and ground surface loads based on mathematical theorems.
