The genus of a smooth complete algebraic curve X is equal to the dimension of the space of regular differential 1-forms on X( cf. Differential form). The genus of an algebraic curve X is equal, by definition, to the genus of the complete algebraic curve birationally isomorphic to X.
An algebraic curve C is the graph of an equation f(x, y) = 0, with points at infinity added, where f(x, y) is a polynomial, in two complex variables, that cannot be factored. Curves are classified by a nonnegative integer—known as their genus, g—that can be calculated from their polynomial.
In mathematics, real algebraic geometry is the sub-branch of algebraic geometry studying real algebraic sets, i.e. real-number solutions to algebraic equations with real-number coefficients, and mappings between them (in particular real polynomial mappings).
An algebraic rule is a mathematical expression that relates two variables and is written in the form of an equation. There are many constant algebraic rules, such as area = length x width. You can also create your own rule when given a set of variables.
In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. A parabola, one of the simplest curves, after (straight) lines. Intuitively, a curve may be thought of as the trace left by a moving point.
Closure Property: When something is closed, the output will be the same type of object as the inputs. For instance, adding two integers will output an integer. Adding two polynomials will output a polynomial. Addition, subtraction, and multiplication of integers and polynomials are closed operations.
The closure property for polynomials states that the sum, difference, and product of two polynomials is also a polynomial. However, the closure property does not hold for division, as dividing two polynomials does not always result in a polynomial. Consider the following example: Let P(x)=x2+1 and Q(x)=x.
When a integer is divided by another integer, the result is not necessarily a integer. Thus, integers are not closed under division.
CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial. Adding polynomials creates another polynomial. Subtracting polynomials creates another polynomail. Multiplying polynomials creates another polynomial.
Property 1: Closure Property The closure property of integers under addition and subtraction states that the sum or difference of any two integers will always be an integer. if p and q are any two integers, p + q and p − q will also be an integer. Example : 7 – 4 = 3; 7 + (−4) = 3; both are integers.
