Abstract:A Tychonoff space A is metrizably fibered if and only if there exists a continuous map View the MathML source onto a metrizable space B such that for each bB,F−1(b) is metrizable. We resolve a question stated by V. Tkachuk by showing that every first countable Hausdorff continuous image of the lexicographic square is metrizably fibered. We also observe that an example of S. Mardeši? and P. Papi? resolves a related question stated by Tkachuk.
