  Strong electron correlations and interference effects are discussed in
capacitively coupled side attached and embedded quantum dots. The finite - U
mean field slave boson approach is used to study many-body effects. In the
linear range the many-body resonances exhibit SU(4) Kondo or Kondo-Fano like
character and their properties in the corresponding arms are close to the
properties of embedded or T- shape double dot systems respectively. Breaking of
the spin symmetry in one of the arms or in both allows for the formation of
many-body resonances of SU(3) or SU(2) symmetries in the linear range.
