In the framework of a field theoretical approach we study Maier-Saupe
nematogenic fluid in contact with a hard wall. The pair interaction potential
of the considered model consists of an isotropic and an anisotropic Yukawa
terms. In the mean field approximation the contact theorem is proved. For the
case of the nematic director being oriented perpendicular to the wall,
analytical expressions for the density and order parameter profiles are
obtained. It is shown that in a certain thermodynamic region the nematic fluid
near the interface can be more diluted and less orientationally ordered than in
the bulk region.Comment: 6 pages, 1 figur
