The graph of minimal distances of bent functions and its properties
TL;DR: It is proven that the graph is connected for2k = 2, 4, 6, disconnected for 2k≥10 and its subgraph induced by all functions EA-equivalent to Maiorana—McFarland bent functions is connected.

Bent functions on the minimal distance
Nikolay Kolomeec,Andrey Pavlov +1 more
TL;DR: It is shown that the minimal Hamming distance in class of bent functions in n variables is equal to 2n/2 and it is proved that two bent functions are at the minimal distance if and only if they differ on an affine subspace and these functions are affine on it.
