We deal with the geometry of a Galois space PG(N, q) of countable dimension. We study subsets of PG(N, 4) with respect to h-dimensional characters. In this context, we characterize the quadrics and the hermitian varieties in PG(N, q).

โฆ Synopsis
In a fundamental paper R.E. Jamison showed, among other things, that any subset of the points of AG(n, q) that intersects all hyperplames contains at least n(q -I) + 1 points. Here we show that the method of proof used by Jamisoa can be applied to several other basic problems in finite geometries of a varied nature. These problems include the celebrated flock theorem and also the characterization of the elements of GF(q) as a set of squares in GF(q z) with certain properties. This last result, due to A. Blokhuis, settled a well-known conjecture due to J,H, vail Lint and the late J. MaeWilliams.

A set of kind s in the Galois space S~,q is a set of points such that any s + 1 are linearly independent but there is at least one subset ofs + 2 linearly dependent points. The packing problem is that of finding m[,~, the largest size of set of kind s in S,,q. The main result is the evaluation of m~
