We consider M(v):, models of Euclidean quantum field theory, P(v) = X',t, akyk and define for them translation-invariant ground states. It appears that the number of them is not more than two provided Xim,2 is large. ## 1. PHASE DIAGRAMS AND GROUND STATES FOR CLASSICAL LATTICE SPIN SYSTEMS Let us

We give sufficient conditions to ensure the existence of isolated one-particle states in the joint energy-momentum spectrum of an Osterwalder-Schrader scalar boson quantum field theory. We do not require the existence of sharp-time fields or weak coupling. We give sufficient conditions to ensure th
A comparative investigation has been conducted of the mechanisms and rate of chemical reactions in thermal and microwave fields. A number of nonpolymer-forming and polymer-forming mixtures of different functionality and molecular architecture were prepared and investigated. The advancement of reacti
