Special zeta values at positive integers are usually expressed in terms of arithmetic invariants, algebraic as well as transcendental. A basic problem is to determine all the algebraic relations among such special values. In particular to prove their algebraic independence when natural algebraic relations could not be found. There is a motivic program of Grothendieck from half century ago toward this end. We shall report on recent progresses of this program in the positive characteristic world.
