Interaction between fluctuations: wavy lines represent the superconducting fluctuators Le/h(q, Ω, T), broken lines stand for magnetic (SDW) fluctuator Dm(q, Ω, T).
Diagrams (a,b) define A coefficient, (c) - B- coefficient, (d,e) - C1 - coefficient, (f,g) - C2 - coefficient. Notations for solid and dashed lines are the same as in Fig. 2.
