Intersection | Operations on sets | Basic concepts in set theory

Intersection (set theory)

In set theory, the intersection of two sets and denoted by is the set containing all elements of that also belong to or equivalently, all elements of that also belong to (Wikipedia).

What is an Intersection? (Set Theory)

What is the intersection of sets? This is another video on set theory in which we discuss the intersection of a set and another set, using the classic example of A intersect B. We do not quite go over a formal definition of intersection of a set in this video, but we come very close! Be su

Union vs Intersection (Set Theory)

What is A union B? What is the union of sets? What is the intersection of sets? I've talked about these topic before, but in this video we will look at unions and intersections of sets side by side. So get ready to learn about these very cool set operations! I hope you find this video he

What is a Union? (Set Theory)

What is A union B? How do you find the union of sets? What is an operation of sets? In this video we answer these questions, we will talk about the simple set operation: the union, what it is, and how to union two sets. I hope you find this video helpful, and be sure to ask any questions d

Finding a Set from its Intersection and Relative Complement | Set Theory

If we are given A intersect B, A-B, and B-A, can we determine what A and B are? We'll be going over this problem in today's set theory lesson with an example that will demonstrate the reasoning necessary to solve this problem! In general, for two sets A and B, A is equal to (A intersect B

Proof: A is a Subset of B iff A intersect B Equals A | Set Theory, Subsets

A is a subset of B if and only if A intersect B equal A. We will prove this set theory result in today's video set theory lesson! The proof is straightforward and follows easily from definitions. Always good to get some practice learning how to use our fundamental set theory definitions

A Union B Equals A Intersect B iff A=B | Set Theory

Let A and B be two sets. Then, A=B if and only if A union B equals A intersect B. We will show this basic biconditional set equality result in today's set theory video lesson. We use what's called "double inclusion", which is just how we prove two sets are equal. To show A=B we prove A is

G. Binyamini - Point counting for foliations over number fields

We consider an algebraic $V$ variety and its foliation, both defined over a number field. Given a (compact piece of a) leaf $L$ of the foliation, and a subvariety $W$ of complementary codimension, we give an upper bound for the number of intersections between $L$ and $W$. The bound depends

Proof: DeMorgan's Laws for Set Complement | Set Theory

DeMorgan's laws for sets tell us how set complement works over set union, and how set complement works over intersection. We'll be proving the two parts of De Morgan's laws in today's set theory video lesson! This is a simple proof using our definitions of set union, set intersection, set
