Area-Preserving Surface Diffeomorphisms [PDF]
Communications in Mathematical Physics, 2006 We prove some generic properties for $C^r$, $r=1, 2, ..., \infty$, area-preserving diffeomorphism on compact surfaces. The main result is that the union of the stable (or unstable) manifolds of hyperbolic periodic points are dense in the surface. This extends the result of Franks and Le Calvez \cite{FL03} on $S^2$ to general surfaces.

Surface Area Determination [PDF]
Nature, 1946 IN the determination of surface area using nitrogen at the temperature of liquid nitrogen by the method of Brunauer, Emmett and Teller1, it is usual to determine the dead-space on each sample, using helium. For routine determinations on a substance known to give S-shaped isotherms, that is, where the equation of Brunauer, Emmett and Teller is ...
