We present a formal approach, using integral equations of the Lippmann-Schwinger type, to the scattering of particles by semiinlinite periodic potentials. The two possible physical situations, scattering of free plane waves and scattering of Bloch waves, are treated with two different integral equat

The most general classical solution with finite action of the N = 1 Gross-Neveu model is found. The use of conformal invariance and the toroidal (S' 0 S')-formalism based upon it are crucial for obtaining these general spinor lield configurations. ## Scalar Field Theories in Curved Space-Time.
We quantize gauge field theories in odd dimensional space-time with actions including both a Chern-Simons term and a Yang-Mills term. Such theories will be referred to as CSYM theories. We show that there are deep connections between these theories and chiral anomalies and current algebra in even di
