Approximate roots of a valuation and the Pierce-Birkhoff Conjecture
François Lucas, James Madden, Daniel Schaub +1
This paper is a step in our program for proving the Piece-Birkhoff Conjecture for regular rings of any dimension (this would contain, in particular, the classical Pierce-Birkhoff c…

A connectedness theorem for real spectra of polynomial rings
François Lucas, James Madden, Daniel Schaub +1
Let R be a real closed field. The Pierce-Birkhoff conjecture says that any piecewise polynomial function f on R^n can be obtained from the polynomial ring R[x_1,...,x_n] by iterati…
