J. Denev, Vladimir D. Tonchev · IEEE Transactions on Information Theory · 1980
An asymptotic estimate is established for the number of equivalence classes of Boolean functions ofnvariables under transformations of the formf(x) \rightarrow f(Ax+b)+ L(x), wherex=(x_{l}, \cdots ,x_{n}), Ais a nonsingularnbynmatrix,bis a vector, andL(x)is a linear function.
