   Format: MarkdownItexPreviously I've said that I've proved that the category $\mathbf{Fcd}$ is cartesian closed. That was a fake alarm: my proof had a crucial error. Now I have set <a href="http://portonmath.tiddlyspace.com/#[[Cartesian%20closedness]]">a wiki to prove it collaboratively</a>, just like problems of Polymath Project.

   Format: MarkdownItexI suggest that you add to the page [[funcoid]] a *succinct* definition of $\mathbf{Fcd}$ (defining both objects and morphisms) that does not require anyone to read your book.

   Format: MarkdownItexOh, it seems that proving cartesian closedness of <b>Fcd</b> is harder than it seemed. In <a href="http://portonmath.tiddlyspace.com/#[[Cartesian%20closedness]]">my wiki</a> I've shown only that all ways to prove it which I considered fail.
