*The theory of minihypers applied to other subjects in geometry*

Sandy Ferret (University of Ghent, Belgium)

Minihypers are multisets in PG(t,q) intersecting a hyperplane
in at least a certain number of points (counted with weights).
We give a classification of certain minihypers and then apply
this theorem to

(1) Linear codes meeting the Griesmer bound

(2) Maximal partial spreads in projective and quadrics

(3) Maximal partial ovoids of H(3,q^2) and the generalized hexagon H(q).
