Stochastic representation of solutions for the parabolic Cauchy problem with variable exponent coefficients

Mustafa Avci

In this work, we prove existence and uniqueness of a bounded viscosity solution for the Cauchy problem of degenerate parabolic equations with variable exponent coefficients. We con…

On the geometric Brownian motion with state-dependent variable exponent diffusion term

Mustafa Avci

We propose a new stochastic model involving state-dependent variable exponent which allows modeling of systems where noise intensity adapts to the current state. This ne…

Three solutions for a double phase variable exponent Kirchhoff problem

Mustafa Avci

In this article, we study a double-phase variable-exponent Kirchhoff problem and show the existence of at least three solutions. The proposed model, as a generalization of the Kirc…

Existence results for the Cox-Ingersoll-Ross model with variable exponent diffusion

Mustafa Avci

This study proposes a new stochastic model where the diffusion coefficient involves a state-dependent variable exponent function . This new theoretically flexible framewo…

Nehari manifold approach for a singular multi-phase variable exponent problem

Mustafa Avci

This paper is concerned with a singular multi-phase problem with variable singularities. The main tool used is the Nehari manifold approach. Existence of at least two positive solu…

Monotone operator methods for a class of nonlocal multi-phase variable exponent problems

Mustafa Avci

In this paper, we study a class of nonlocal multi-phase variable exponent problems within the framework of a newly introduced Musielak-Orlicz Sobolev space. We consider two problem…
