On Solutions of a Generalization of the Goła̧b–Schinzel Functional Equation

On locally bounded above solutions of an equation of the Goła̧b–Schinzel type

“…and proved that solutions of this equation can be described by solutions of a partially pexiderized Go lab-Schinzel equation 6) considered in several papers (a bibliography can be found in the survey paper [7]) and very recently in papers [1] and [10]. For the first time Eq.…”

Goła̧b–Schinzel equation on cylinders

“…Several results concerning this problem can be found e.g. in [2], [4][5][6][7], [11,12], [14,15] and [17][18][19]. All of them concern the case where an unknown function f is a real function of a real variable.…”

Continuous Solutions of Conditional Composite Type Functional Equations

“…has been considered among others in [10,21,22] and [24]. Some further results concerning conditional Go lab-Schinzel type functional equations can be found in [5,6,8,12,25] and [26].…”
