Quadratic forms | Field (mathematics)
In mathematics, the universal invariant or u-invariant of a field describes the structure of quadratic forms over the field. The universal invariant u(F) of a field F is the largest dimension of an anisotropic quadratic space over F, or β if this does not exist. Since formally real fields have anisotropic quadratic forms (sums of squares) in every dimension, the invariant is only of interest for other fields. An equivalent formulation is that u is the smallest number such that every form of dimension greater than u is isotropic, or that every form of dimension at least u is universal. (Wikipedia).

Andrea Colesanti: An overview on a young research topic: valuations on spaces of functions
I will start from the theory of valuations on convex bodies, which for me was the main motivation to study corresponding functionals in an analytic setting. Then I will devote some time to the notion of valuations on a space of functions. After a general review on this topic, I will descri
