Let A be a set with m elements and B a set of n elements, where m; n are positive integers. Find the number of one-to-one functions from A to B.

Let S be a set and P be a property of the elements of the set,...

Let S be a set and P be a property of the elements of the set, such that each element either has property P or not. For example, maybe S is the set of your classmates, and P is "likes Japanese food." Then if s ∈ S is a classmate, he/she either likes Japanese food (so s has property P) or does not (so s does not have property P). Suppose Pr(s has property P) = p for a uniformly...

Let x be a set and let R be a relation on x such x is simultaneously reflexive, symmetric, and antisymmetric. Prove equivalence relation.

Provide an example: 1) A sequence with infinitely many terms equal to 1 and infinitely many terms that are not equal to 1 that is convergent. 2) A sequence that converges to 1 and has exactly one term equal to 1. 3) A sequence that converges to 1, but all of its terms are irrational numbers.

Let S be a set of n numbers. Let X be the set of all subsets...

Let S be a set of n numbers. Let X be the set of all subsets of S of size k, and let Y be the set of all ordered k-tuples (s1, s2, , sk) such that s1 < s2 < < sk. That is, X = {{s1, s2, , sk} | si S and all si's are distinct}, and Y = {(s1, s2, , sk) | si S and s1 < s2 < < sk}. (a) Define a one-to-one correspondence f : X → Y. Explain...

Let X be an uncountable set, let τf be the finite complement topology on X, and let τc be the countable complement topology; namely, we have τf ={U⊂X : X\U is finite}∪{∅}, τc={U⊂X : X\U is countable}∪{∅}, where “countable” means that the set is either finite or countably infinite (in bijection with the natural numbers). (a) What are the compact subspaces of (X, τf )? Are all compact subspaces closed in (X, τf )? (b) What are the compact subspaces...

Let D(x, y) be the predicate defined on natural numbers x and y as follows: D(x, y) is true whenever y divides x, otherwise it is false. Additionally, D(x, 0) is false no matter what x is (since dividing by zero is a no-no!). Let P(x) be the predicate defined on natural numbers that is true if and only if x is a prime number. 1. Write P(x) as a predicate formula involving quantifiers, logical connectives, and the predicate D(x,...
