Query: New fixed point theorems for set-valued contractions in b-metric spaces   In this paper we indicate a way to generalize a series of fixed point results
in the framework of b-metric spaces and we exemplify it by extending Nadler's
contraction principle for set-valued functions (see Multi-valued contraction
mappings, Pac. J. Math., 30 (1969), 475-488) and a fixed point theorem for
set-valued quasi-contractions functions due to H. Aydi, M.F. Bota, E. Karapinar
and S. Mitrovic (see A fixed point theorem for set-valued quasi-contractions in
b-metric spaces, Fixed Point Theory Appl. 2012, 2012:88).
