In mathematics, a homogeneous function is a function of several variables such that, if all its arguments are multiplied by a scalar, then its value is multiplied by some power of this scalar, called the degree of homogeneity, or simply the degree; that is, if k is an integer, a function f of n variables is homogeneous of … Meer weergeven The concept of a homogeneous function was originally introduced for functions of several real variables. With the definition of vector spaces at the end of 19th century, the concept has been naturally extended to functions … Meer weergeven Homogeneity under a monoid action The definitions given above are all specialized cases of the following more general … Meer weergeven • Homogeneous space • Triangle center function – Point in a triangle that can be seen as its middle under some criteria Meer weergeven Simple example The function $${\displaystyle f(x,y)=x^{2}+y^{2}}$$ is homogeneous of degree 2: Meer weergeven The substitution $${\displaystyle v=y/x}$$ converts the ordinary differential equation Meer weergeven Let $${\displaystyle f:X\to Y}$$ be a map between two vector spaces over a field $${\displaystyle \mathbb {F} }$$ (usually the real numbers $${\displaystyle \mathbb {R} }$$ or complex numbers $${\displaystyle \mathbb {C} }$$).
