The effective potential augments the classical potential with the quantum effects of
virtual particles, and permits the study of spontaneous symmetry breaking.
In contrast to the standard approach where the classical potential already leads to
electroweak symmetry-breaking, the Coleman-Weinberg mechanism explores
quantum corrections as the source of symmetry-breaking.
This thesis explores
extensions of the Coleman -Weinberg mechanism to the situations with more than one Higgs doublet.
These multi-Higgs models have a long history , and occur most naturally in the
Minimal Supersymmetric model.
Mathematical foundations of the zeta function method will be developed and then applied
to regularise the one-loop computation of the effective potentials in a model with two scalar fields.
