The field-theoretical model describing multicritical phenomena with two coupled order parameters with n || and n⊥ components and of O(n||) ⊕ O(n⊥) symmetry is considered. Conditions for realization of different types of multicritical behaviour are studied within the field-theoretical renormalization...
