  We study the interaction corrections to the transport coefficients in open
quantum dots (i.e. dots connected to leads of large conductance $G \gg
e^2/\pi\hbar$), via a quantum kinetic equation approach. The effects of all the
channels of the universal (in the Random Matrix Theory sense) interaction
Hamiltonian are accounted for at one loop approximation. For the electrical
conductance we find that even though the magnitude of the triplet channel
interaction is smaller than the charging energy, the differential conductance
at small bias is greatly affected by this interaction. Furthermore, the
application of a magnetic field can significantly change the conductance due to
the Zeeman splitting, producing finite bias anomalies. For the thermal
conductance we find that the Wiedemann-Franz law is violated by the interaction
corrections, and we investigated the effect of magnetic field on the Lorentz
ratio for contacts of finite reflection. The charge and triplet channel
corrections to the electrical and thermal conductance vanish for reflectionless
contacts. In the latter case the temperature and magnetic field dependence of
the conductance is determined by the Maki-Thompson correction in the Cooper
channel.
