  • Epsilon-expansion in the N-component φ4 model 
    Missarov M.; Stepanov R. (2006)
    The formalism of projection Hamiltonians is applied to the N-component O(N)-invariant φ4 model in the Euclidean and p-adic spaces. We use two versions of the ε-expansion (with ε = 4 - d and with ε = α - 3d/2, where α is ...
  • ε-expansions in Dyson's hierarchical model 
    Missarov M.; Stepanov P. (2004)
    We consider Dyson's hierarchical model on a d-dimensional hierarchical lattice and define a renormalization group (RG) transformation for complex values of d as a map in the space of sequences of coupling constants determining ...
