In mathematics, the degree of a polynomial is the highest of the degrees of the polynomial's monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer .
This definition coincides with the algebraic topological definition above. The same definition works for compact manifolds with boundary but then f should send the boundary of X to the boundary of Y. One can also define degree modulo 2 (deg 2 (f)) the same way as before but taking the fundamental class in Z 2 homology.
Let C be a curve of degree d in P 3, then consider all the lines in P 3 that intersect the curve C. This is a degree d divisor D C in G(2, 4), the Grassmannian of lines in P 3. When C varies, by associating C to D C, we obtain a parameter space of degree d curves as a subset of the space of degree d divisors of the Grassmannian: Chow(d,P 3).
def – define or definition. deg – degree of a polynomial, or other recursively-defined objects such as well-formed formulas. (Also written as ∂.) del – del, a differential operator. (Also written as.) det – determinant of a matrix or linear transformation. DFT – discrete Fourier transform.
The function in example 1, a removable discontinuity. Consider the piecewise function = {< = >. The point = is a removable discontinuity.For this kind of discontinuity: The one-sided limit from the negative direction: = and the one-sided limit from the positive direction: + = + at both exist, are finite, and are equal to = = +.
In mathematics, a polynomial is a mathematical expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication and exponentiation to nonnegative integer powers, and has a finite number of terms.
This is a glossary of properties and concepts in category theory in mathematics. (see also Outline of category theory.). Notes on foundations: In many expositions (e.g., Vistoli), the set-theoretic issues are ignored; this means, for instance, that one does not distinguish between small and large categories and that one can arbitrarily form a localization of a category.

In mathematics, a characteristic class is a way of associating to each principal bundle of X a cohomology class of X.The cohomology class measures the extent to which the bundle is "twisted" and whether it possesses sections.
