1896, Ludwig Boltzmann: Boltzmann refutes Poincare and Zermelo.
1896, Ernest Zermelo: Zermelo replies to Boltzmann's refutation, and reasserts that kinetic theory contradicts Poincare's recurrence theorem.
Basically Zermelo correctly asserts that Boltzmann's argument is not on firm mathematical while his argument is, but goes on to incorrectly assert that it follows that Boltzmann is wrong.

This system is one that was devised largely by Ernest Zermelo, and so it is often called Zermelo-Fraenkel set theory (ZF) or sometimes just set theory.
The core of Zermelo's solution to Russell's paradox is that set theory does not have an unlimited comprehension principle for sets.
Instead Zermelo's set theory introduced a modified form of the comprehension principle, called the subset axioms, which allows us to construct the required sets, to show that the required sets exist, without deriving a contradiction.

Hilbert's search for new rules of inference in his proof theory, Gödel's search for new axioms and Zermelo's infinitary logic are presented as attempts to overcome this gap.
The use of simile or analogy is frequently adopted by mathematicians in their attempt to explain features of mathematical knowledge to the general public.
Proposing social constructivism as a novel philosophy of mathematics, this book is inspired by current work on sociology of knowledge and social studies of science.

 BLACK-BODY PROBLEMATIC:
GENESIS AND STRUCTURE
Another objection to the H-Theorem came in 1896 from Ernest Zermelo, Planck’s assistant in Berlin, who developed what has since been known as the ‘recurrence paradox’.
Applying a mathematical theorem published by Poincare five years ago, Zermelo argued that any mechanical system confined in a finite region of space would after a sufficiently long time ultimately return to its initial configuration.
However, Planck disagreed with Zermelo’s contention that the entropy law as a natural law is really incompatible with every mechanical interpretation of nature.

The response to the paradox that is generally accepted in today’s world was developed by Ernest Zermelo and modified by Abraham Fraenkel.
Zermelo’s approach was like Cantor’s, in that he used an axiomatic approach (the formal term is axiomatizaion of set theory).
Fraenkel took Zermelo’s theory and fine-tuned to the approach we generally use today.

The breadth and depth of disagreement on the most fundamental issues between individuals who on the face of it might be expected to see eye to eye on the bases, if not more, of their common subject of interest is a continual source of fascination to me.
Paul Ernest's remarks, which I very much enjoyed reading, are a case in point.
Therefore I interpret a social philosophy of mathematics as Paul Ernest describes it, as inevitably flawed by its deliberate avoidance of vast amounts of data about 'the activity and products of persons', and its reliance on very selective use of data.

A number is a set; a group is a set; and anything that mathematics can effectively talk about should be a set or a collection of sets.
Today, the concept of a set has been given a more rigorous definition, mainly by the axiomatization of set theory by Ernest, Zermelo (1871-1953) and Adolf Abraham, Fraenkel (1891-1965).
Sets, in this view, are any classes which can be proved to be sets using the axioms.

If you do not object to the preceding sentence, then read on.
Axiomatic Set Theory (AST) lays down the axioms of the now-canonical set theory due to Zermelo, Fraenkel (and Skolem), called ZFC.
The axiom schema that is used explicitly in the book is the "axiom schema of separation" due to Ernst Zermelo, which he formulated in order to make precise the notion of a statement as being "definite".

 Some observations about Hilbert
In a lecture in 1929, Hilbert explicitly added the completeness of arithmetic as a challenge to future mathematicians.
One of the junior professor at Gottingen, Ernest Zermelo, pointed out to Hilbert in 1904, independently and in parallel with Russell, a paradox of set theory: "The set of all sets that are not members of themselves." This raised grave doubts about set theory as it existed then.
Hilbert was adamently opposed to the position of an earlier mathematician named Kronecker who had insisted that only constructive mathematics was appropriate.

Finally, Cournot’s justification for his solution had some unattractive underlying assumptions that ended up convincing economists that although Cournot had the right answer, he did not have the right logic to justify his answer.
 SHAPE \* MERGEFORMAT  Von Neumann and Morgenstern: two-player zero-sum games Mathematicians such as James Waldegrave (in 1713), Ernest Zermelo (in 1913), Emile Borel (in 1921-27), and John von Neumann (in 1928) had begun to look at decision-making in parlor games—such as poker, tic-tac-toe, and chess—as the subject of serious mathematical analysis.
However, it was not until Oskar Morgenstern, an economist, collaborated with von Neumann to write The Theory of Games and Economic Behavior in 1944 that the problem of rational behavior by interdependent players began to be seen as central to economics.

Set theory solves the problem of infinity rather simply by introducing an axiom of infinity which Ernest Zermelo formulated as: <$Epile {{down 30 font 2 symbol $} above {italic X}} ~(~ 0 ~symbol
The axiom uses a generation rule established by recursive definitions, hence no pretense was made that an infinite set can be generated outside theory, as Dedekind attempted to do.
Zermelo introduces such an infinite set by a simple fiat, indicating how new elements can be derived from those already in X; but the existence of such an infinite set is ascertained from the outset.
