Title: | Generalized solutions for inextensible string equations | Authors: | Şengül, Yasemin Vorotnikov, Dmitry |
Issue Date: | 2017 | Publisher: | Elsevier | Project: | info:eu-repo/grantAgreement/FCT/5876/147205/PT | Serial title, monograph or event: | Journal of Differential Equations | Volume: | 262 | Issue: | 6 | Abstract: | We study the system of equations of motion for inextensible strings. This system can be recast into a discontinuous system of conservation laws as well as into the total variation wave equation. We prove existence of generalized Young measure solutions with non-negative tension after transforming the problem into a system of conservation laws and approximating it with a regularized system for which we obtain uniform estimates of the energy and the tension. We also discuss sufficient conditions for non-negativity of the tension for strong solutions. | URI: | https://hdl.handle.net/10316/43808 | DOI: | 10.1016/j.jde.2016.11.040 10.1016/j.jde.2016.11.040 |
