The comb-like representations of cellular ordinal balleans

I. V. Protasov, K. D. Protasova

Given two ordinal $\lambda$ and $\gamma$, let $f:[0,\lambda )\to [0,\gamma )$ be a function such that, for each $\alpha <\gamma$, $\sup \{f(t):t\in [0,\alpha ]\}<\gamma .$ We define a mapping $d_{f}: [0,λ)\times [0,λ)…
