In mathematics, specifically algebraic geometry, a scheme is a structure that enlarges the notion of algebraic variety in several ways, such as taking account of multiplicities (the equations x = 0 and x 2 = 0 define the same algebraic variety but different schemes) and allowing "varieties" defined over any commutative ring (for example, Fermat curves are defined over the integers).
In mathematics, the Séminaire de Géométrie Algébrique du Bois Marie (SGA; from French: "Seminar on Algebraic Geometry of Bois Marie") was an influential seminar run by French mathematician Alexander Grothendieck.
The Éléments de géométrie algébrique (EGA; from French: "Elements of Algebraic Geometry") by Alexander Grothendieck (assisted by Jean Dieudonné) is a rigorous treatise on algebraic geometry that was published (in eight parts or fascicles) from 1960 through 1967 by the Institut des Hautes Études Scientifiques.
An axiom schema is a formula in the metalanguage of an axiomatic system, in which one or more schematic variables appear. These variables, which are metalinguistic constructs, stand for any term or subformula of the system, which may or may not be required to satisfy certain conditions.
Rigor is a cornerstone quality of mathematics, and can play an important role in preventing mathematics from degenerating into fallacies. well-behaved An object is well-behaved (in contrast with being Pathological ) if it satisfies certain prevailing regularity properties, or if it conforms to mathematical intuition (even though intuition can ...
By definition, a morphism of schemes is just a morphism of locally ringed spaces. Isomorphisms are defined accordingly. A scheme, by definition, has open affine charts and thus a morphism of schemes can also be described in terms of such charts (compare the definition of morphism of varieties). [1] Let ƒ:X→Y be a morphism of schemes.
In mathematics, the Bernoulli scheme or Bernoulli shift is a generalization of the Bernoulli process to more than two possible outcomes. [ 1 ] [ 2 ] Bernoulli schemes appear naturally in symbolic dynamics , and are thus important in the study of dynamical systems .
In French, means 'sophisticated' or 'delicate', or simply 'studied', without the negative connotations of the English. rendezvous lit. "present yourself" or "proceed to"; a meeting, appointment, or date in French. In English, it generally endorses a mysterious overtone and refers to a one-on-one meeting with someone for another purpose than a date.
