Sets defined in algebraic terms
Webset, in mathematics and logic, any collection of objects (elements), which may be mathematical (e.g., numbers and functions) or not. A set is commonly represented as a list of all its members enclosed in braces. The intuitive idea of a set is probably even older than that of number. Members of a herd of animals, for example, could be matched with … Web24 Apr 2024 · Q = {m / n: m ∈ Z and n ∈ N + } is the set of rational numbers. A = {x ∈ R: p(x) = 0 for some polynomial p with integer coefficients} is the set of algebraic numbers. Note that N + ⊂ N ⊂ Z ⊂ Q ⊂ A ⊂ R. We will also occasionally need the set of complex numbers C = {x + iy: x, y ∈ R} where i is the imaginary unit.

Web24 Mar 2024 · An algebraic set is the locus of zeros of a collection of polynomials. For example, the circle is the set of zeros of x^2+y^2-1 and the point at (0,0) is the set of zeros of x and y. The algebraic set {(x,0)} union {(0,y)} is the set of solutions to xy=0. It decomposes into two irreducible algebraic sets, called algebraic varieties. In general, an algebraic set …
Sets in mathematics, are simply a collection of distinct objects forming a group. A set can have any group of items, be it a collection of numbers, days of a week, types of vehicles, and so on. Every item in the set is called an element of the set. Curly brackets are used while writing a set.
