In this thesis an algebraic structure, called real calculus, is used as a way to represent noncommutative manifolds in an algebraic setting. Several classical geometric concepts are defined for real calculi, such as metrics and affine connections, and real calculus homomorphisms are introduced. These homomorphisms are then used to define embeddings of real calculi representing manifolds, anda notion of minimal embedding is introduced. The motivating example of the thesis is the noncommutative torus as embedded into a localization of the noncommutative 3-sphere, where it is shown that the noncommutative torus is a minimal embedding of the noncommutative 3-sphere for certain perturbations of the standard metric.
