Abstract:We develop a homotopical variant of the classic notion of an algebraic theory as a tool for producing deformations of homotopy theories. From this, we extract a framework for constructing and reasoning with obstruction theories and spectral sequences that compute homotopical data starting with purely algebraic data. We investigate the algebra necessary to apply this to examples of interest, such as to E-infinity rings with good theories of power operations. As an application, we give some tools for working with K(h)-local E-infinity algebras over a Lubin-Tate spectrum of height h, and use these to produce new E-infinity complex orientations at heights h <= 2.
