Thermodynamic
and transport properties of a two-dimensional circular quantum dot
are studied theoretically at zero magnetic field. In the limit
of a large confining potential, where the dot spectrum exhibits
a shell structure, it is argued that both spectral and transport
properties should exhibit Luttinger liquid behavior. These predictions
are verified by direct numerical diagonalization. The experimental
implications of such Luttinger liquid characteristics are discussed.

By comparing to the full diagonalization
for a small number of electrons, we can estimate the error in the minimal
energy for a given angular momentum due to the subspace reduction to be
less than 1%.
