If X is a log space, let X be X with the trivial log structure.
Geometry of schemes
Did you know?
In mathematics, a scheme is a mathematical structure that enlarges the notion of algebraic variety in several ways, such as taking account of multiplicities (the equations x = 0 and x = 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). Scheme theory was introduced by Alexander Grothendieck in 1960 in his treatise "Éléments de g… WebSchool of Mathematics School of Mathematics

Webscheme: [noun] a mathematical or astronomical diagram. a representation of the astrological aspects of the planets at a particular time. a graphic sketch or outline.
WebThis is a flat family. You can see this geometrically, as the fiber over t is a hyperbola when t ≠ 0, and as t approaches 0, the hyperbola gets sharper and sharper and then it "breaks" into two lines when t = 0. Constrast this example with Spec ( k [ x, y, t] / ( t x y − t)) → Spec ( k [ t]). This is not a flat family.
