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)Reply

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