A Nonsymplectic Manifold with an Injective Universal Moment Map
Friday, April 19, 2013
 
Exercise : This is an addendum to the Note 2 of the article 9.23, page 323 of the TextBook, made as an exercise with a detailed solution. This example shows how the hypothesis of transitivity of the group of automorphisms is necessary in the statement 9.23. There is a mistake in a coefficient in the computation of a moment which doesn’t affect the result but needed to be fixed. It was an opportunity to develop the computation. ../The%20Book.htmlshapeimage_2_link_0
Diffeology — Erratum — Page 324, in Proof of art. 9.23, the line before the last line: read 2π/4 instead of 2π/3.
