“lazy” nonstandard analysis, in which the implied ultrafilter is never actually constructed as a “completed object“, but is instead lazily evaluated, in the sense that whenever membership of a given subsequence of the natural numbers in the ultrafilter needs to be determined, one either ...

Requiring that a floating-point representation be normalized makes the representation unique. Unfortunately, this restriction makes it impossible to represent zero! A natural way to represent 0 is with 1.0 × , since this preserves the fact that the numerical ordering of nonnegative real numbers ...
But for now, I just want to write about one alternative way of capturing the idea of a “group with the identity element forgotten”, which was described in a blog post by Matt Baker. Baker introduces the notion of a proportion space, which is a non-empty set equipped with an ...
