Noncommutative Algebra and Noncommutative Geometry
Abstract
Divided into three parts, the first marks out enormous geometric issues with
the notion of quasi-freenss of an algebra and seeks to replace this notion of
formal smoothness with an approximation by means of a minimal unital
commutative algebra's smoothness. The second part of this text is then, devoted
to the approximating of properties of nc. schemes through the properties of two
uniquely determined (classical) schemes estimating the nc. scheme in question
in a maximal way from the inside and through the minimal scheme approximating
the nc. scheme in question from the outside. The very brief final par of this
exposition, aims to understand and distil the properties at work in
constructing any "scheme-like" object over an "appropriate" category, purely
out of philosophical interest.
