Direct Systems of Spherical Functions and Representations
Spherical representations and functions are the building blocks for harmonic
analysis on riemannian symmetric spaces. In this paper we consider spherical
functions and spherical representations related to certain infinite dimensional
symmetric spaces . We use the
representation theoretic construction where is a
--fixed unit vector for . Specifically, we look at
representations of where is
--spherical, so the spherical representations and the
corresponding spherical functions are related by where is a --fixed unit vector for , and we
consider the possibility of constructing a --spherical function
. We settle that matter by proving the equivalence
of condtions (i) converges to a nonzero --fixed vector ,
and (ii) has finite symmetric space rank (equivalently, it
is the Grassmann manifold of --planes in \F^\infty where and
\F is , \C or \H). In that finite rank case we also prove the
functional equation
of Faraut and Olshanskii, which is their definition of spherical functions.Comment: 17 pages. New material added on the finite rank case

Auditors\u27 Third Party Liability: An Ill-Considered Extension of the Law
Numerous legal commentators have recently advocated an extension of auditors\u27 professional liability to third-party users of financial statements, with the dual purposes of inducing improved disclosure in financial statements and obtaining restitution for investors injured by misleading statements, and some judicial decisions have adopted such an expanded liability. This comment evaluates the probable effectiveness and effects of such expanded liability, concluding that the expansion is unlikely to obtain either of its stated objectives and that such an expansion is likely to create pressures upon the cost and availability of audits which will be injurious to both investors and users of capital and will impede the resource-allocating capability of the economy
