Symmetry breaking has a central role in particle physics. Flat (Minkowski) space is a useful abstraction in most cases, but to study the real world, one must at some point consider nonzero spacetime curvature. Inflationary models in cosmology are an example where spacetime curvature and symmetry breaking together form the basis of the evolution of physics. In the first part of the thesis we examine symmetry breaking in a particular quantum state in de Sitter space, the vacuum state associated with the ``static'' system. In the second part, we develop a framework for the effective potential method in de Sitter space, and check that it stays correct in the low curvature limit.
