Solution solute in a solution is the mass of that solute expressed as a percentage of the mass of the whole solution. "Homogeneous" means that the components of the mixture form a single phase. "Heterogeneous" means that the components of the mixture are of different phase. The properties of the mixture (such as concentration, temperature, and density) can be uniformly distributed through the volume but only in absence of diffusion phenomena or after their completion. Usually, the substance present in the greatest amount is considered the solvent. Solvents can be gases, liquids or solids. One or more components present in the
Quasi-homogeneous polynomial Quasi-homogeneous polynomial In algebra, a multivariate polynomial is quasi-homogeneous or weighted homogeneous, if there exist "r" integers formula_2, called weights of the variables, such that the sum formula_3 is the same for all nonzero terms of "f". This sum "w" is the "weight" or the "degree" of the polynomial. The term "quasi-homogeneous" comes from the fact that a polynomial "f" is quasi-homogeneous if and only if for every formula_5 in any field containing the coefficients. A polynomial formula_6 is quasi-homogeneous with weights formula_2 if and only if is a homogeneous polynomial in the formula_9. In particular, a homogeneous polynomial is
