Talk:Variational analysis

Developing this article into a proper overview of the subject
Rockafellar and Wets' *Variational Analysis* is a deep book with wide ranging coverage of topics, including:


 * Compactification of Euclidean spaces
 * Set convergence and set-valued functions
 * Modes of function convergence with good optimization structure
 * "Variational" geometry, subdifferential calculus, Lipschitzian properties
 * Duality
 * Measurability

Additionally, there is a lot of literature that deals with non Euclidean spaces and more general analysis.

In view of this literature it seems a shame that the Wikipedia article itself is essentially a stub. I think we should try to expand it, and connect it to topics which already exist in Wikipedia. InfCompact (talk) 18:22, 30 March 2020 (UTC)


 * Agreed. I just wanted to note here that for any nonnegative integer n, $$\mathbb T^n=\operatorname{hzn}\mathbb R^{n+1}$$: the oriented projective space / two-sided space of oriented projective geometry is the same thing as what Rockafellar-Wets calls the "horizon" of $$\mathbb R^{n+1}$$ (Chapter 3).
