Ten problems on quadratic forms
The 27-dimensional module for E6. I.
The Pythagoras number of some affine algebras and local algebras.
The quadratic form transfer and valuations.
The u-invariant of fields with 16 and 32 square classes I
We discuss here the conjectures of Kaplansky and of Lam concerning the ii-univariant of a field of characteristic different from two. Both conjectures are shown t.o hold true for any field having at most 32 square classes.
The Witt group of quadratic characters.
Twisted Pfister forms.
