We discuss some of the implications of simulating QCD when the action used for the sea quarks is different from that used for the valence quarks. We present exploratory results for the hadron mass spectrum and pseudoscalar meson decay constants using

Normally, a lattice is introduced to regulate a strong-coupling expansion in quantum field theory. We investigate a class of alternative continuum regulation schemes and show that they fail.

We study two continuum methods of regulating the formal strong-coupling expansion of the Green's functions, obtained by expanding the path integral in powers of the kinetic energy (inverse free propagator). Our continuum regulations amount to introdu

The two-dimensional planar model in the presence of either constant or random symmetry-breaking fields, which locally select p preferred directions, undergoes two phase transitions for certain values of p . A systematic renormalization of the sine-Go

We derive from the path integral a continuum strong-coupling expansion for QED in $d$-dimensional Euclidean space-time. It is a double expansion in the fermion and boson kinetic energy (inverse free propagators), which leads to a double power series
