Example of fiber bundle that is not a fibration - MathOverflow
Such a fibration is said to be locally trivial. For the Hopf fibration, it is enough to remove a single point m from S 2 and the corresponding circle p −1 (m) from S 3; thus one can take U = S 2 \{m}, and any point in S 2 has a neighborhood of this form. Geometric interpretation using rotations Zobacz więcej In the mathematical field of differential topology, the Hopf fibration (also known as the Hopf bundle or Hopf map) describes a 3-sphere (a hypersphere in four-dimensional space) in terms of circles and an ordinary sphere. … Zobacz więcej For any natural number n, an n-dimensional sphere, or n-sphere, can be defined as the set of points in an $${\displaystyle (n+1)}$$-dimensional space which are a fixed distance from … Zobacz więcej The Hopf fibration has many implications, some purely attractive, others deeper. For example, stereographic projection S → R induces a … Zobacz więcej • "Hopf fibration", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Rowland, Todd. "Hopf fibration". MathWorld.

We are interested in studying the variation of the Hitchin fibration in moduli spaces of parabolic Higgs bundles, under the action of a ramified covering. Given a degree two map π: Y → X between compact Riemann surfaces, we may pull back a Higgs bundle from X to Y, the lifted Higgs bundle tends to have many … Witryna20 paź 2024 · This paper discusses the main minimalist theory within the Minimalist Program, something I dub the (Weak) Merge Hypothesis (MH).
