Let $\scr{T}$ be the first order theory of diagonalizable algebras. We define a bijection φ from the atomic formulas of $\scr{T}$ (identities) to the open formulas of $\scr{T}$. φ is an algebraic ...
Studia Logica publishes original papers on various logical systems, which utilize methods of contemporary formal logic (those of algebra, model theory, proof theory, etc.). More specifically, Studia ...
