Bent functions on partial spreads.
To appear in Designs, Codes and Cryptography (published online 9 April 2013).
For an arbitrary prime p we use
partial spreads of Fp2m to construct
two classes of bent functions from Fp2m
to Fp.
Our constructions generalize the classes PS(-) and PS(+)
of binary bent functions which are due to Dillon.
