Applications of Klee's Dehn-Sommerville relations

Isabella Novik, Ed Swartz

We use Klee's Dehn-Sommerville relations and other results on face numbers of homology manifolds without boundary to (i) prove Kalai's conjecture providing lower bounds on the f-ve…

f-Vectors of 3-Manifolds

Frank H. Lutz, Thom Sulanke, Ed Swartz

In 1970, Walkup completely described the set of $f$ -vectors for the four 3-manifolds $S^{3}$ , $S^{2} tw i s t S^{1}$ , $S^{2} \times S^{1}$ , and $R P^{3}$ . We improve one of Walkup's main restricti…
