Topic: Delta epsilon definition of limits


  
 Continuous Article, Continuous Information   (Site not responding. Last check: 2007-10-31)
In order theory,especially in domain theory, one considers a notion derived from thisbasic definition, which is known as Scott continuity.
If c is an accumulation point of the domain, thenthe limit of f(x) as xapproaches c must exist and be equal to f(c).
The above definitions of continuous functions can be generalized to functions from one topological spaces to another in a natural way; a function f : X →Y, where X and Y are topological spaces, is continuous iff forevery open set V ⊆ Y, f

The limit of f(x) as x approaches c must exist and be equal to f(c).
The usual (easier) proof makes use of the axiom of choice, but in the case of real functions it was proved by Wacław Sierpiński that the axiom of choice is not actually needed.
On the other hand, since the limit of g at 0 is 1, g can be extended continuously to R by defining its value at 0 to be 1.

The limit of f(x), as x approaches c, must exist
The limit of f(x), as x approaches c, must equal f(c)
This can also be formulated in terms of sequences and limits: the function f is continuous at the point c if and only if for every sequence (x

 Aristotle and the science of Being qua Being (1)
Next, in book Delta, comes Aristotle's "philosophical lexicon": some forty philosophical terms are explained and their different senses shortly set out and illustrated.
Book Epsilon is brief: it returns to the science of being qua being, and also passes some remarks on truth.
This is to ask whether in addition to investigating the definitions of the per se accidents of substance, it will also study such issues as whether each contrary has a single contrary.
