scheme theory

noun2

1. •
   The branch of mathematics that concerns schemes (locally ringed spaces admitting coverings by open sets, each isomorphic to the spectrum of some commutative ring).
2. •
   A theory of group decision-making which explains group decisions as the result of a decision scheme on the initial distribution of attitudes in the group.

   • With these ideas of scheme theory, perturbation, and abstraction, it becomes possible to see how metacognition might be interpreted in constructivist terms. — 1998
