WebFeb 9, 2024 · For any morphism of varieties f: C 1 C 2, there is an induced morphism f # on the structure sheaves of C 1 and C 2, which are locally ringed spaces. If C 1 and C 2 are curves, then the stalks are one dimensional regular local rings and therefore discrete valuation rings, so in this way we recover the algebraic geometric definition (Definition 3 ) … WebA monomorphism is said to be regular if it is an equalizer of some pair of parallel morphisms.

WebSep 5, 2024 · We also generalize Ehrlich’s Theorem on one-sided unit regular morphisms by showing that if N is an M-regular object, then a morphism f: M → N is left (right) unit regular if and only if there exists a split monomorphism (epimorphism) Ker (f) → Coker (f). We also study regular morphisms determined by generalized inverses in additive ...

In commutative algebra, a G-ring or Grothendieck ring is a Noetherian ring such that the map of any of its local rings to the completion is regular (defined below).

Together, these define a group structure on the variety. The above morphisms are often written using ordinary group notation: μ(f, g) can be written as f + g, f⋅g, or fg; the inverse ι(g) can be written as −g or g −1. the golden pagodaIn the particular case that Y equals A the regular map f:X→A is called a regular function, and are algebraic analogs of smooth functions studied in differential geometry. The ring of regular functions (that is the coordinate ring or more abstractly the ring of global sections of the structure sheaf) is a fundamental object in affine algebraic geometry. The only regular function on a projective variety is constant (this can be viewed as an algebraic analogue of Liouville's theorem in complex … theater like recliners for home
