Whitney maps-a non-metric case [PDF]
Colloquium Mathematicum, 2000 Summary: It is shown that there is no Whitney map on the hyperspace \(2^X\) for non-metrizable Hausdorff compact spaces \(X\). The authors present examples of non-metrizable continua \(X\) which admit and such which do not admit a Whitney map for \(C(X)\).

Lagrange mappings of the first open Whitney umbrella [PDF]
Pacific Journal of Mathematics, 2002 A Lagrange variety of a symplectic manifold \(E\) of dimension \(2n\) is a subset \(\Lambda\) of \(E\) that admits a statification into strata of dimension at most \(n\) such that the symplectic form of \(E\) vanishes on each of the strata. Given a Lagrange variety \(\Lambda\subset E\), two Lagrange fibrations \(\pi, \pi':E\to Y\) over a smooth ...

Group-Twisted Alexander-Whitney and Eilenberg-Zilber Maps [PDF]
Algebras and Representation Theory, 2020 We define group-twisted Alexander-Whitney and Eilenberg-Zilber maps for converting between bimodule resolutions of skew group algebras. These algebras are the natural semidirect products recording actions of finite groups by automorphisms. The group-twisted chain maps allow us to transfer information between resolutions for use in homology theories ...

Journal of Learning Development in Higher Education, 2014 àThis paper considers issues around the support and retention of mature and part-time (MaP) students. It analyses the specific academic development needs of MaP students based on Wengerââ¬â¢s model of learning (1998) which puts the academic ...

Extending generalized Whitney maps [PDF]
Archivum Mathematicum, 2017 For metrizable continua, there exists the well-known notion of a Whitney map. If X is a nonempty, compact, and metric space, then any Whitney map for any closed subset of 2X can be extended to a Whitney map for 2X [3, 16.10 Theorem]. The main purpose of this paper is to prove some generalizations of this theorem.

Whitney theorem for complex polynomial mappings [PDF]
Mathematische Zeitschrift, 2019 We describe the topology of a general polynomial mapping $F=(f, g):X\to\Bbb C^2$, where $X$ is a complex plane or a complex sphere.

Whitney regularity of the image of the Chevalley mapping [PDF]
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2016 A compact set K ⊂ ℝn is Whitney 1-regular if the geodesic distance in K is equivalent to the Euclidean distance. Let P be the Chevalley map defined by an integrity basis of the algebra of polynomials invariant by a reflection group. This paper gives the Whitney 1-regularity of the image by P of any closed ball centred at the origin.
