Thisthesisdealswithlocalizedstructuresinfieldtheoryinbothflatandcurvedspacetime. Initially, we investigate the presence of kinklike solutions in (1,1) dimensions in models with a single real scalar field and present a route to compactify them. Moreover, by extending the study to generalized models, we seek for conditions so that the models are twins, with the same solutions, energy densities and stabilities up to an arbitrary order, present a Born-Infeld-like model and reveal a class of models that share the same energy density and stability. Next, in (2,1) dimensions, we introduce a first order formalism in order to study vortices in Maxwell-Higgs and Chern-Simons-Higgs models. By using this formalism, we show a path to compactify the vortex a...
