  Homogeneous
Homogenization is intensive mixing of mutually insoluble phases (sometimes with addition of surfactants) to obtain a soluble suspension or emulsion, for example homogenizing milk so that the cream doesn't separate out.
In physical chemistry, homogeneous describes a single-phase system as opposed to a heterogeneous system.
In the context of procurement/purchasing, homogeneous is used to describe goods that do not vary in their essential characteristic irrespective of the source of supply.

  Mathematics Program at Bard College | Program Overview
Mathematics is at the core of human civilization and is the cornerstone of all modern science and technology.
For example, when each senior mathematics major engages in a year-long research program for her senior project, she is not required to work on whatever interests the professor— contrast to student research at many other colleges and universities.
At Bard all senior projects in mathematics are individually tailored to meet the interests of the students; indeed, the topics for senior projects are often suggested by the students themselves, with guidance from the faculty.

 The Effects of Homogeneous Groupings in Mathematics. ERIC/CSMEE Digest.
The practice of homogeneous grouping, which is quite widespread in the United States, uses a model that typically groups students together on ability or achievement as the deciding variable.
The persistence of homogeneous grouping is particularly troubling given the long-term effects on female and minority students, both groups of whom are dramatically underrepresented in the mathematics and science areas.
Recent assessments in mathematics achievement suggest students in the United States are not generally strong in mathematics, with too few students, especially minority and female, studying higher level mathematics.

The average sixth-grade CAT Mathematics percentiles for the CPMP students and those in the traditional curriculum are similar as shown in Table 2, so these two groups were well-matched on mathematical achievement prior to high school.
The Mathematics Placement Test, compiled from a bank of items developed by the Mathematical Association of America, that is presently used at a major university was administered in several field-test schools in May 1999 at the end of CPMP Course 4 and traditional Precalculus courses.
The mathematics courses are 105/110 (precalculus), 115 (calculus I), 116 (calculus II), 215 (calculus III), 216 (introduction to differential equations), and honors (all honors math courses open to freshmen).

 CSMEE Digest 93-6   (Site not responding. Last check: 2007-10-29)
At the high school level, this practice is most prevalent in mathematics, where students are placed in vocational, general, or college-preparatory mathematics courses (McPartland, Coldiron, & Braddock, 1987; Oakes, 1985, 1990a, 1990b; Slavin, 1990).
While it is true that tracking at earlier grade levels may limit the numbers of students eligible to take college-preparatory mathematics coursework, the end result is that many students are denied access to important mathematics experiences which prepares them to pursue the study of mathematics and science beyond high school.
Here, the research has been inconclusive, with several studies of regrouping for mathematics instruction showing that homogeneous regrouping had positive effects on mathematics achievement when materials appropriate for the student's level of performance were used (Provus, 1960; Morris,1969).

 Does Homogeneous = Separable?
But it looks like it could be homogeneous non-linear (if such a thing exists, I don't know???).
that is "homogeneous" in this sense: P(x) dy/dx+ Q(x)y= 0 is trivially seperable: dy/y= -(Q(x)/P(x))dx.
A(x,y)dx+ B(x,y)dy= 0 is "homogeneous" if and only if B(andlamda;x,andlamda;y)/A(andlambda;x, andlambda;y)= B(x,y)/A(x,y) (essentially that means that the total exponent of x and y in each term is the same).
