Boolean inner-product spaces and Boolean matrices

Abstract: This article discusses the concept of Boolean spaces endowed with a Boolean valued inner product and their matrices. A natural inner product structure for the space of Boolean n-tuples is introduced. Stochastic boolean vectors and stochastic and unitary Boolean matrices are studied. A dimension theorem for orthonormal bases of a Boolean space is proven. We characterize the invariant stochastic Boolean vectors for a Boolean stochastic matrix and show that they can be used to reduce a unitary matrix. Finally, we… Show more

“…The map x → x (rk) is bijective because (x (rk) ) (rk) = x by Lemma 4.8 (6) and (B4). The map is a homomorphism: t r (x, y, z) (rk) = L.4.8 (7) t r (x, y (rk) , z (rk) ) = t r ((x (rk) ) (rk) , y (rk) , z (rk) ) = q((x (rk) ) (rk) , y (rk) /r, z (rk) /r) = L.4.8 (4) q(x (rk) , y (rk) /k, z (rk) /k) = t k (x (rk) , y (rk) , z (rk) ). Moreover, (e r ) (rk) = e (rk)r = e k .…”

“…An R-semimodule is called: (i) a module if R is a ring; (ii) a vector space if R is a field; (iii) a Boolean vector space (see [9] for basic facts on Boolean vector spaces) if R is a Boolean algebra. The elements of an R-semimodule are called vectors.…”
