Tsen rank Tsen rank In mathematics, the Tsen rank of a field describes conditions under which a system of polynomial equations must have a solution in the field. The concept is named for C. C. Tsen, who introduced their study in 1936. We consider a system of "m" polynomial equations in "n" variables over a field "F". Assume that the equations all have constant term zero, so that (0, 0, ... ,0) is a common solution. We say that "F" is a T-field if every such system, of degrees "d", ..., "d" has a common non-zero solution whenever The "Tsen rank" of
