We found a solution of Henry E. Dudeney’s star puzzle (a path on a chessboard from c5 to d4 in 14 straight strokes) in 14 queen moves, which was claimed impossible by the puzzle author. Generalizing this result to other board sizes, we obtained bou

Let $X$ be a real separable normed space $X$ admitting a separating polynomial. We prove that each continuous function from a subset $A$ of $X$ to a real Banach space can be uniformly approximated by restrictions to $A$ of functions which are analyti

The approximation of continuous functions on countable normed Frechet spaces by analytic and *-analytic functions is considered. We also determine a criterion for the existence of an extension of a continuous function from a dense subspace of a topol
