Fixed point results and the Ekeland variational principle in vector -metric spaces
Radu Precup, Andrei Stan
In this paper, we extend the concept of \( b \)-metric spaces to the vectorial case, where the distance is vector-valued, and the constant in the triangle inequality axiom is repla…

On equilibrium in control problems with applications to evolution systems
Radu Precup, Andrei Stan
In this paper we examine a mutual control problem for systems of two abstract evolution equations subject to a proportionality final condition. Related observability and semi-obser…

Role of partial functionals in the study of variational systems
Andrei Stan
Applying techniques originally developed for systems lacking a variational structure, we establish conditions for the existence of solutions in systems that possess this property b…
