Query: Permanent confinement in the compact QED3 with fermionic matter   We argue that the compact three dimensional electrodynamics with massless
fermions is always confining, in spite of the bare interaction between the
magnetic monopoles being rendered logarithmic by fermions. The effect is caused
by screening by other dipoles, which transforms the logarithmic back into the
Coulomb interaction at large distances. Possible implications for the chiral
symmetry breaking for fermions are discussed, and the global phase diagram of
the theory is proposed.
