I updated online article “Pointfree Funcoids” from “preliminary draft” to just “draft”. This means that it was somehow checked for errors and ready for you to read. (No 100% warranty against errors however.)
Having finished with that draft the way is now free for my further Algebraic General Topology research, such as n-ary (multidimensional) funcoids, direct product of funcoids, limits of discontinuous functions, etc.
