NPC - Non-positive curvature group actions and cohomology
If R, k and K are the polynomial ring, fraction field and Laurent series field in one variable over a finite field, we prove that the continued fraction expansions of Hecke sequences of quadratic irrationals in K over k behave in sharp contrast with the zero characteristic case. This uses the ergodic properties of the action of the diagonal subgroup of PGL on the moduli space PGL / PGL and the action of the lattice PGL on the Bruhat-Tits tree of PGL . (Joint work with Uri Shapira)
