A logical space is a pair $${(A, {\mathcal{B}})}$$ of a non-empty set A and a subset $${{\mathcal{B}}}$$ of $${{\mathcal{P}} A}$$ . Since $${{\mathcal{P}} A}$$ is identified with {0, 1}A and {0, 1} is a typical lattice, a pair $${(A, {\mathcal{F}})}$$ of a non-empty set A and a subset $${{\mathcal{F}}}$$ of $${{\mathbb{B}}^A}$$ for a certain lattice $${{\mathbb{B}}}$$ is also called a $${{\mathbb{B}}}$$ -valued functional logical space. A deduction system on A is a pair (R, D) of a subset D of…
