- Title
Quasi-classical Theory of the A-phase of Superfluid He-A in a Cylinder.

- Abstract
We develop a quasi-classical theory to study the A-phase texture with a coreless vortex like the Mermin-Ho texture in a cylinder. We consider both the cases of cylinder with specular surface and diffusive surface. In case of the diffusive surface, we find a Mermin-Ho type texture at higher temperatures but with the order parameter suppressed near the surface. In the case of specular surface, however, we find a surface correction to the order parameter. The mass current distribution and the total angular momentum are also discussed.
