What is the Roster Method? (Roster Form) | Set Theory, Writing Sets, Expressing Sets

The roster method is one of several set notations you can use to write a set. It is perhaps the easiest understand, but is only useful for writing out sets when they are finite and small in size, or if they are dictated by an easy to describe pattern (that is finite or infinite). If you ar

Introduction to sets || Set theory Overview - Part 1

A set is the mathematical model for a collection of different things; a set contains elements or members, which can be mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other #sets. The #set with no element is the empty

How to Identify the Elements of a Set | Set Theory

Sets contain elements, and sometimes those elements are sets, intervals, ordered pairs or sequences, or a slew of other objects! When a set is written in roster form, its elements are separated by commas, but some elements may have commas of their own, making it a little difficult at times

What are Signed Graphs?

This video introduces signed graphs and signed graph theory. Signed graphs are graphs where the edges are given a positive or negative sign. They see applications in scheduling (signed graph coloring specifically), data science, social psychology, and more. In future videos we'll look at c

Data Structures and Polygonal Splines | Algebraic Calculus One | Wild Egg

In this video we introduce polygonal splines, through a preliminary discussion of data structures. Then we extend our notion of signed areas from polygons to polygonal splines. Along the way we introduce cyclic oriented data structures, together with a special notation for cyclic lists a

Mateusz Skomora: Separation theorems in signed tropical convexities

The max-plus semifield can be equipped with a natural notion of convexity called the “tropical convexity”. This convexity has many similarities with the standard convexity over the nonnegative real numbers. In particular, it has been shown that tropical polyhedra are closely related to the
