The product of two modal logics L1 and L2 is the modal logic determined by the class of frames of the form FG such that F and G validate L1 and L2, respectively. This paper proves...

We consider a modal language for affine planes, with two sorts of formulas (for points and lines) and three modal boxes. To evaluate formulas, we regard an affine plane as a Kripke...
