Conservation of Number PrincipleA generalization of Poncelet's Permanence of Mathematical Relations Principle made by H. Schubert in 1874-79. Theconservation of number principle asserts that the number of solutions of any determinate algebraic problem in any number ofparameters under variation of the parameters is invariant in such a manner that no solutions become Infinite. Schubert called the application of this technique the Calculus of Enumerative Geometry. See also Duality Principle, Hilbert's Problems, Permanence of MathematicalRelations Principle
