In mathematics , formal moduli are an aspect of the theory of moduli space s of algebraic varieties or vector bundle s, for example , closely linked to deformation theory and formal geometry . Roughly speaking, deformation theory can provide the Taylor polynomial level of information about deformations, while formal moduli theory can assemble consistent Taylor polynomials to make a formal power series theory. The step to moduli spaces, properly speaking, is an algebraization question, and has been largely put on a firm basis by Artin s approximation theorem . A formal universal deformation is by definition a formal scheme over a complete local ring , with special fiber the scheme over a field being studied, and with a universal property amongst such set ups. The local ring in question is then the carrier of the formal moduli. References Springer id d d030700 title Deformation Category Moduli theory ... more details

Formal ethics is a formal logical system for describing and evaluating the form as opposed to the content of ethical principles. Formal ethics was introduced by Harry J.

Formal ethics is related to ethical formalism in that its focus is the forms of moral judgments, but the exposition in Formal Ethics makes it clear that Gensler, unlike previous ethical formalists, does not consider formal ethics to be a complete ethical theory such that the correct form would be necessary and sufficient for an ethical principle to be correct .
