“…The following proposition was proved in [15] in the case that (s, t) = (4, 2). Using analogous arguments one can show that it holds in the case that (s, t) = (3, 3) as well.…”
G-deformability of maps into projective space is characterised by the existence of certain Lie algebra valued 1-forms. This characterisation gives a unified way to obtain well known results regarding deformability in different geometries.

“…In [8,17] it is shown thatf is also a Lie applicable surface and that f is an m-Darboux transform off . Thus we say that ( f,f ) is an m-Darboux pair.…”

“…Blaschke [3] showed that together these surfaces are the applicable surfaces of Lie sphere geometry. In [12,16] it is shown that these surfaces constitute an integrable system and this is given a gauge theoretic interpretation in [8,17]. This gives rise to a Lie-geometric analogue of the Darboux transformation for these surfaces.…”
We investigate curved flats in Lie sphere geometry. We show that in this setting curved flats are in one-to-one correspondence with pairs of Demoulin families of Lie applicable surfaces related by Darboux transformation.
“…We call f an m-Darboux transform of f . In [8,17] it is shown that f is also a Lie applicable surface and that f is an m-Darboux transform of f . Thus we say that (f, f ) is an m-Darboux pair.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
