We study a complex system of partial integro-differential equations (PIDE) of parabolic type modeling the option pricing problem in a regime-switching jump diffusion model. Under suitable conditions, we prove the existence of solutions of the PIDE sy

Option pricing with transaction costs leads to a nonlinear Black-Scholes type equation where the nonlinear term reflects the presence of transaction costs. Under suitable conditions, we prove the existence of weak solutions in a bounded domain and we

This work is devoted to the study of the elliptic equation $Delta u = f(x,u)$ in a bounded domain $Omegasubset mathbb{R}^n$ with a nonlinear boundary condition. We obtain various existence results applying coincidence degree theory and the method of

We study the elliptic boundary-value problem $$displaylines{ Delta u + g(x,u) = p(x) quad hbox{in } Omega cr uig|_{partial Omega} = hbox{ m constant}, quad int_{partialOmega} frac {partial u}{partial u} = 0, }$$ where $g$ is $T$-periodic in $u$, and

We establish conditions for existence and for nonexistence of nontrivial solutions to an elliptic system of partial differential equations. This system is of gradient type and has a nonlinearity with critical growth.

We study a semilinear second-order ordinary differential equation with initial condition $u(0)=u_0$. We prove the existence of solutions satisfying a nonlinear final condition $u(T)=h'(u(T))$, under a certain growth condition. Also we state condition

We use minimax methods to prove the existence of at least three solutions for a quasilinear elliptic equation in $mathbb {R}^n$ near resonance.

An analysis is made of the land use transformations over the last sixty years, as well as the consequences of these transformations on the naturalness of the territories of three municipalities of the “Nuovo Circondario Imolese” (Bologna, Italy).
