Nega-Hadamard Transform, Bent and Negabent Functions

In this paper we start developing a detailed theory of nega– Hadamard transforms. Consequently, we derive several results on negabentness of concatenations, and partially-symmetric functions. We also obtain a characterization of bent–negabent functions in a subclass of Maiorana–McFarland set. As a by-product of our results we obtain simple proofs of several existing facts.
