MAA245 NUMBERS 1 Natural Numbers, N

... N is a set with the properties:(i) ∃ an element denoted “1” in N; so N is non-empty. (ii) There is a function S : N → N called the Successor Function. Thus, ∀ n ∈ N, ∃ S(n) ∈ N. Write S(1) = 2, S(2) = 3, . . .. (iii) 1 6= S(n) for any n ∈ N; i.e. 1 is not the successor of any element of N. (iv) S(m) ...

... The combinatorial arguments of the construction can then be replaced by equational reasoning in KA. As it turns out, this connection will allow us to obtain powerful completeness metatheorems in later sections. A string rewriting system R over a finite alphabet Σ consists of rules δ ∈ r, where δ and ...

... Group theory is an important part of modern algebra. The concept of “group” was first put forward by the young French mathematician Galois (E. Galas, 1811-1832) and only defined the permutation group. Abstract group can be perceived as a collection of a class of objects, which have binary operator r ...

LECTURE NOTES ON SETS Contents 1. Introducing Sets 1 2

... Practically speaking, this amounts to the following: if S is a set and x is any object, then exactly one of the following must hold: x ∈ S or x ∈ / S. That’s the point of a set: if you know exactly what is and is not a member of a set, then you know the set. Thus a set is like a bag of objects...but ...

... Got92, Van89]. In case of formalisms admitting variables and, more generally, infinite recursive propositional nonmonotonic formalisms, a number of results has been found. These include basic complexity results for Horn logic [Smu68, AN78], the complexity of the perfect model semantics of stratified ...

... The study of congruence properties of the general partition function p(n) has been a wellspring of mathematical research from the moment Ramanujan [9] first made his ground breaking studies nearly eighty years ago. Inspired by Ramanujan’s work, the results of Watson,[10] Atkin,[3] Dyson,[4] and Andr ...

Moreover, we will see that the Hausdorff dimension of Eφ will decay to zero if the speed of φ(n) is growing faster and faster, which can be treated as a supplement to Wu and Xu [19], Liao and Rams [13], and Ma [14] in this topic.
