Local distributions for eigenfunctions and for perfect colorings of q-ary hypercube
Anastasia Vasil'eva
Under study are the eigenfunctions and perfect colorings of the graph of -dimensional -ary Hamming space. We obtain the interdependence of local distributions of an eigenfunc…

Reconstruction of Eigenfunctions of q-ary n-dimensional Hypercube
Anastasia Vasil'eva
Under study are eigenfunctions of -ary -dimensional hypercube. Given all values of an eigenfunction in the sphere we develop methods to reconstruct the function in full or in…
