On the Mathematical Modelling of the Annihilation Process
Using field-theoretic approach the reaction process A + A → ∅ is studied in the vicinity of space dimension d c = 2 by means of the perturbative renormalization group. Dimensional regularization with the use of minimal subtraction scheme is applied and fixed points with corresponding regions of stability are calculated to the two-loop approximation in double (ε,Δ) expansion.
