Web1 de ago. de 2013 · The aim of this paper is to establish the H 1 global well-posedness for Kirchhoff systems. The new approach to the construction of solutions is based on the … WebIn Section 3 local existence theorems together with H˙-well-posedness in the sense of Hadamard are discussed. In Section 4 a uniform energy estimate for global in time analytic solutions in a suitable Sobolev space is proved. After that, absolute integrability of time-derivative of the coffit of equation is proved. Section 5

WebAbstract. We consider the Kirchhoff equation ∂ t t u − Δ u ( 1 + ∫ T d ∇ u 2) = 0 on the d -dimensional torus T d, and its Cauchy problem with initial data u ( 0, x), ∂ t u ( 0, x) of size ε in the Sobolev class. The effective equation for the dynamics at the quintic order, obtained in previous papers by quasilinear normal form ... WebFollowing physical considerations, we allow m(·) to be any non-decreasing, non-negative continuous function (a degenerate Kirchhoff string). We assume that the initial value u 0 satisfies: m (〈 Au 0 , u 0 〉)>0 (a mildly degenerate Kirchhoff string), that m is locally Lipschitz continuous in the open region where it does not vanish, and that m has a finite … Web13 de fev. de 2024 · Arosio, A. and Panizzi, S.
