Superpositions of continuous functions defined on a Baire space
S. S. Marchenkov, S. I. Krivospitsky M. V. Lomonosov Moscow State University, Faculty of Computational Mathematics and Cybernetics
Abstract:
We consider uniformly continuous functions on a Baire space and introduce the notion of a continuity modulus of a function. We formulate a condition on the growth of the continuity modulus $\varphi$ guaranteeing that superpositions of $n$-ary functions with continuity modulus $\varphi$ do not exhaust all $(n+1)$-ary functions with continuity modulus $\varphi$ for any $n$. Moreover, negating this property leads to the inverse effect.
