          Absztract: There are many new systems where 2 order parameters 
          compete with each other. Of particular interest are systems in 
which both     
          order parameters are unconventional. We examine the case of d-wave 
          superconductivity in the presence of d-wave density wave as in high 
Tc
          cuprate superconductivity in the underdoped region. We construct a 
low 
          energy effective Hamiltonian and draw the phase diagram of high Tc 
cuprate 
          superconductivity within the mean field theory. The quasiparticle 
density 
          of states, superfluid density, etc., are calculated and confronted 
with 
          some of the experimental data.
