extinction processes: maps that decrease probability and terminate random walks

Linear operators that map would have been interesting to Turing – where the termination condition is the “indistinguishability” of relative proportions found in inputs steams from the uniform distribution produce in the output stream.


See intro.pdf

From the very form of the Tunny-era ”algebra of proportional bulges” we are starting to see which intellectual tradition Turing and co were using, as they founded their particular branch of cryptanlysis. The more I understand good presentations of generating functions of sigma-algebras and the distinction between finite models of quantum mechanism vs infinite modes (that beg things like banach spaces and lie groups) the more we are getting inside the head of the 1940s cryptanalytical thinkers – finally realizing in empirically work the intellectual achievements the 1920-30s.
