Boolean homomorphisms of a hypercube, which correspond to the morphisms in the category of finite Boolean algebras, coincide with the linear isometries of the category of finite binary metric vector ...

In many problems of combinatory analysis, operations of addition of sets are used (sum, direct sum, direct product etc.). In the present paper, as well as in the preceding one [1] , some properties of ...

Abstract: Nonlinearity is an important index for a Boolean function to be used in stream cipher systems. We design fast algorithm for nonlinearity of Boolean function. Boolean addition used in this ...
