Abstract

The existence of a decomposition space with a dendritic structure of a topological space ({0,1}Λ,τ0Λ)(\{0,1\}^\Lambda ,\tau_{0}^\Lambda ) is discussed. Here, Λ\Lambda is any set with the cardinal number ,{0,1}Λ={φ:Λ{0,1}},τ0\succ \aleph , \{0,1\}^{\Lambda }=\{\varphi :\Lambda \rightarrow \{0,1\}\}, \tau_0 is the discrete topology for {0,1}\{0,1\} and the topology τ0Λ\tau_0^{\Lambda } for {0,1}Λ\{0,1\}^\Lambda is the topology with the base β={<Gλ1,,Gλn> ; Gλ1τ0,,Gλnτ0,{λ1,,λn}Λ,nN}\beta =\{<G_{\lambda _1},\dots,G_{\lambda _n}>~;~G_{\lambda_1}\in \tau_0,\dots,G_{\lambda _n}\in \tau_0, \{\lambda _1,\dots,\lambda _n\}\subset \Lambda ,n\in {\bf N}\} where the notation <Eλ1,,Eλn><E_{\lambda _1},\dots,E_{\lambda _n}> concerning the subset Eλi,i=1,,nE_{\lambda _i}, i=1,\dots,n of {0,1}\{0,1\} denotes the set {φ:Λ{0,1} ; φ(λ1)Eλ1,,φ(λn)Eλn,φ(λ){0,1},λΛ{λ1,,λn}}\{\varphi :\Lambda \rightarrow \{0,1\}~;~\varphi (\lambda _1)\in E_{\lambda _1},\dots,\varphi (\lambda _n)\in E_{\lambda _n}, \varphi (\lambda )\in \{0,1\}, \lambda \in \Lambda -\{\lambda _1,\dots,\lambda _n\}\}.
