Sorting algorithms as recursive functions

This paper is an experiment in presenting programming algorithms as recursive functions, without pseudo-code or genuine code. The algorithms presented are the standard basic sorting algorithms with some computational complexity analysis. The style is that of ordinary working mathematics although

Data structures and algebra

[Edited 9/10] There’s an easy connection between data structures and basic abstract algebra that may or may not mean anything, but keeps getting rediscovered. I’ve never seen it clearly explained (anyone with a reference or who notices an error in
