Title: Functional tetrahedron equation and related structures

Abstract: We show how the functional tetrahedron equation appears, together with its solutions, from almost nothing -- lines in a plane and simple linear algebra. Then, a discrete-time dynamical system arises naturally, with an algebraic curve conserved in time, and divisors moving linearly along their Picard group. Finally, a reduction of this system is constructed, for which the conserved quantities turn into the partition function of an inhomogeneous six-vertex free-fermion model.
