Abstract:
The exact renormalized-group equation for a local free energy functional is investigated for arbitrary dimension d of space in the
interval 2⩽d⩽4. There is found to be a unique physical branch of the solution d=3 for a stable fixed point, and the properties of this solution are investigated. For d<3 there are found to be additional branches of the solution corresponding to multicritical behavior described by (φ2)k theories of different orders k.
