On systems of equations with unknown multifunctions related to the plurality function

Let $T$ be a nonempty set. Inspired by a problem posed by Z. Moszner in [10] we investigate for which additional assumptions put on multifunctions $Z(t):Tightarrow 2^{R(m)},$ which fulfil condition
 $$
 igcup_{t in T} Z(t)=R(m),
 $$
 and the system of conditions&#...
