This paper presents new findings from our study in situ of a small Christian church, known as Göreme 31, which is situated above the Kılıçlar church in Göreme (Cappadocia, Turkey). It was discovered and briefly described at the beginning of the

A function f is LC-continuous if the inverse image of any open set is a locally closed set, i.e., an intersection of an open set and a closed set. It is well known that each LC-continuous function f is countably continuous. We prove that f is finitel

A resolvably measurable function is a real-valued function for which the preimage of each open set is resolvable. It is shown that resolvably measurable functions f : X ⊂ R → Y ⊂ R (a subclass of Δ 2 0 -measurable functions) have a decompositi

A map f : X → Y is said to be w-covering if for every ordinal α and every compact S ⊂ Y such that the α-th Cantor derivative ( S ) α of S is a singleton { y } there is a compact subset E of X such that f ( E ) ⊂ S and ( f ( E ) ) α = { y }

Adding to the previous results by the author and using some generalization of sequences, we study a special case of countable decomposability of functions: representation of functions as open, closed and continuous ones with the possible exception of
