Blow-up of solutions for a logarithmic quasilinear hyperbolic equation with delay term 

Pişkin, Erhan; Yüksekkaya, Hazal (Univ. Prithtines, 2021)
In this work, we deal with a logarithmic quasilinear hyperbolic equation with delay term. Under suitable conditions, we get blow up of solutions in a finite time. Our results are more general than the earlier results.

Existence and blow up of solutions for a strongly damped Petrovsky equation with variable-exponent nonlinearities 

Antontsev, Stanislav; Ferreira, Jorge; Pişkin, Erhan (Texas State University, 2021)
In this article, we consider a nonlinear plate (or beam) Petrovsky equation with strong damping and source terms with variable exponents. By using the Banach contraction mapping principle we obtain local weak solutions, ...

Blow up and global existence of solution for a riser problem with logarithmic nonlinearity 

Irkıl, Nazlı; Pişkin, Erhan (Yıldız Technical University, 2021)
In this work, we analyze the influence of the logarithmic source term on solutions to quasilinear riser equation. Firstly, we prove blow up results. Later, we obtain that solutions are global with negative initial energy.

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 nonexistence of global solutions for a plate equation with time delay 

Yüksekkaya, Hazal; Pişkin, Erhan (Yıldız Technical University, 2021)
In this article, we study a plate equation with frictional damping, nonlinear source and time delay. Firstly, we establish the local existence by using the semigroup theory. Then, under suitable conditions, we prove the ...
