Bent functions and line ovals
نویسنده
چکیده
In this paper we study those bent functions which are linear on elements of spreads, their connections with ovals and line ovals, and we give descriptions of their dual bent functions. In particular, we give a geometric characterization of Niho bent functions and of their duals, we give explicit formula for the dual bent function and present direct connections with ovals and line ovals. We also show that bent functions which are linear on elements of inequivalent spreads can be EA-equivalent.

On Existence (Based on an Arithmetical Problem) and Constructions of Bent Functions
Bent functions are maximally nonlinear Boolean functions. They are wonderful creatures introduced by O. Rothaus in the 1960’s and studied firstly by J. Dillon since 1974. Using some involutions over finite fields, we present new constructions of bent functions in the line of recent Mesnager’s works. One of the constructions is based on an arithmetical problem. We discuss existence of such bent ...
متن کاملSpecial Days on Combinatorial Constructions Using Finite Fields
Balanced generalized weighing matrices include well-known classical combinatorial objects such as Hadamard matrices and conference matrices. They have an interesting interpretation in Finite Geometries, and in this context they generalize notions like projective planes admitting a full elation or homology group. We give some general background discussing these connections. Next, we present an e...
متن کاملOn the dual of (non)-weakly regular bent functions and self-dual bent functions
For weakly regular bent functions in odd characteristic the dual function is also bent. We analyse a recently introduced construction of nonweakly regular bent functions and show conditions under which their dual is bent as well. This leads to the definition of the class of dual-bent functions containing the class of weakly regular bent functions as a proper subclass. We analyse self-duality fo...
متن کاملNew infinite families of p-ary weakly regular bent functions
The characterization and construction of bent functions are challenging problems. The paper generalizes the constructions of Boolean bent functions by Mesnager [33], Xu et al. [40] and p-ary bent functions by Xu et al. [41] to the construction of p-ary weakly regular bent functions and presents new infinite families of p-ary weakly regular bent functions from some known weakly regular bent func...
متن کاملConstructing bent functions and bent idempotents of any possible algebraic degrees
Bent functions as optimal combinatorial objects are difficult to characterize and construct. In the literature, bent idempotents are a special class of bent functions and few constructions have been presented, which are restricted by the degree of finite fields and have algebraic degree no more than 4. In this paper, several new infinite families of bent functions are obtained by adding the the...
