Dejenere sönüm terimli evolüsyon denklemlerin çözümlerinin davranışı
Ekinci, Fatma (Dicle Üniversitesi, Fen Bilimleri Enstitüsü, 2021)Bu tezin ilk bölümünde fen ve mühendislik gibi uygulamalı bilimlerde ortaya çıkan evolüsyon denklemlere kısaca değinilmiştir. Ayrıca nitel davranış (qualitative theory) ile ilgili kısa bir bilgi verilmiştir. İkinci ... -
Existence, blow up and growth of solutions for a coupled quasi-linear viscoelastic Petrovsky equations with degenerate damping terms
Ekinci, Fatma; Pişkin, Erhan; Zennir, Khaled (Analytic Publ. Co., 2021)We consider a quasilinear coupled system of two viscoelastic equations with degenerate damping and source terms under Dirichlet boundary condition. We obtain the global existence, blow up and exponential growth of solutions ... -
Global existence of solutions for a coupled viscoelastic plate equation with degenerate damping terms
Pişkin, Erhan; Ekinci, Fatma (Tbilisi Centre Mathematical Science, 2021)We consider a coupled viscoelastic plate nonlinear equations with degenerate damping terms on a bounded domain in R-n. We establish the global existence results under different conditions. -
Growth of solutions for fourth order viscoelastic system
Ekinci, Fatma; Pişkin, Erhan (Yıldız Technical University, 2021)We consider a system of viscoelastic equations with degenerate damping and source terms under Dirichlet boundary condition. We prove the exponential growth of solutions under some restrictions on the initial data, relaxation ... -
Local existence and blow-up of solutions for coupled viscoelastic wave equations with degenerate damping terms
Pişkin, Erhan; Ekinci, Fatma; Zennir, Khaled (Serbian Society of Mechanics, 2020)In this paper, we investigate a nonlinear system of viscoelastic equations with degenerate damping and source terms in a bounded domain. Under appropriate assumptions on the parameters, degenerate damping terms and the ... -
Qualitative analysis of solutions for a Kirchhoff-type parabolic equation with multiple nonlinearities
Pişkin, Erhan; Ekinci, Fatma (Hacettepe University Faculty of Science, 2021)In this work, the local and global existence of weak solutions by using the Faedo-Galerkin method, the finite time blow up of the weak solution with positive initial energy and the general decay of the solution are ...
