Research is reported on seven different topics. The topics include dynamical symmetry breaking and confinement, dynamical symmetry breaking and technicolor, small x-behavior of structure functions and applications in astrophysics and collider physics, chiral soliton physics, new approximation methods in quantum mechanics and field theory, dynamical polarization effects in QCD, and improved development of the ''effective-W'' approximation with new applications to collider physics. The infrared singular part of the gluon propagator produces confined behavior in the quark propagator. New techniboson production and decay rates were calculated which would be detectable at supercollider energies. Simple, analytic expressions were developed for gluon and quark structure functions at small x and large Q/sup 2/, and it was shown that nu N-scattering is greatly enhanced at astrophysical energies, that b-quark production estimates are unreliable because input values at small x, small Q/sup 2/ are unknown, and showed how different input at small x, small Q/sup 2/ feeds through to large Q/sup 2/ regions. Detailed soliton wavefunctions were developed in a field theory context, and applied to show evaluation of matrix elements of hadronic currents. The effect of energy dependence of phases in elastic p-p collisions affected Farrar's program is shown.
