Search for zeros of functionals, fixed points, and mappings coincidence in quasi-metric spaces
The present paper extends previous research of the author to \((b_1, b_2)\)-quasimetric spaces as defined by \textit{A.~V. Arutyunov} and \textit{A.~V. Greshnov} [Izv. Math. 82, No.~2, 245--272 (2018; Zbl 1401.54023); translation from Izv. Ross. Akad. Nauk, Ser.but Mat. 82, No.~2, 3--32 (2018)]. The article promises a lot in the title, but the assumptions of the theorems proven in the paper appear hard to verify in practice.
