We establish conditions under which Baire measurable solutions f of Γ ( x , y , | f ( x ) - f ( y ) | ) = Φ ( x , y , f ( x + φ 1 ( y ) ) , . . . , f ( x + φ N ( y ) ) ) defined on a metrizable topological group are continuous at zero.

On a weak form of uniform convergence

Jaroslav Fuka, Petr Holický (2005)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

The notion of Δ -convergence of a sequence of functions is stronger than pointwise convergence and weaker than uniform convergence. It is inspired by the investigation of ill-posed problems done by A.N. Tichonov. We answer a question posed by M. Katětov around 1970 by showing that the only analytic metric spaces X for which pointwise convergence of a sequence of continuous real valued functions to a (continuous) limit function on X implies Δ -convergence are σ -compact spaces. We show that...
