The residue theorem and its applications - Harvard University
Webb1 feb. 2013 · By the purity theorem, U is simply connected. So any étale covering of X is generically trivial (because its pullback on U is trivial), hence trivial since X is normal. In fact, this proves that if X and Y (both proper and normal) are birationally equivalent, and Y is regular and simply connected, then X is simply connected. Informally, an object in our space is simply connected if it consists of one piece and does not have any "holes" that pass all the way through it. For example, neither a doughnut nor a coffee cup (with a handle) is simply connected, but a hollow rubber ball is simply connected. In two dimensions, a circle is not simply … Visa mer In topology, a topological space is called simply connected (or 1-connected, or 1-simply connected ) if it is path-connected and every path between two points can be continuously transformed (intuitively for embedded spaces, … Visa mer A topological space $${\displaystyle X}$$ is called simply connected if it is path-connected and any loop in $${\displaystyle X}$$ defined … Visa mer • Fundamental group – Mathematical group of the homotopy classes of loops in a topological space • Deformation retract – Continuous, position-preserving mapping from a topological … Visa mer A surface (two-dimensional topological manifold) is simply connected if and only if it is connected and its genus (the number of handles of the surface) is 0.

Complex Analysis - what makes a simple connected set?
Webb6 juni 2024 · The concept and terminology as described above come from the theory of functions of a complex variable. On the other hand, in (algebraic) topology one defines an $ n $- connected space as a space $ X $ such that any mapping from a sphere $ S ^ {m} $, $ m \leq n $, into $ X $ is homotopic to zero.
