So I’m reading an article in New Scientist about problems nailing down the #HubbleConstant and I thought, if the universe is expanding, as in adding new space where there already is some, why isn’t everything expanding with it? All I can think of is, it’s gravity doing it, keeping localized bits of matter together, from subatomic particles to galaxies in size, essentially fighting an epic, m…

Somehow I went all these years without acquiring this record, until today. Apparently this lp was inspired by a Dean Stockwell script for a movie that never got produced.

Abstract: This letter introduces the novel concept of Painlev\'e solitons -- waves arising from the interaction between Painlev\'e waves and solitons in integrable systems. Painlev\'e solitons may also be viewed as solitons propagating against a Painlev\'e wave background, in analogy with the established notion of elliptic solitons, which refer to solitons on an elliptic wave background. By employing a novel symmetry decomposition method aided by nonlocal residual symmetries, we explicitly construct (extended) Painlev\'e II solitons for the Korteweg-de Vries (KdV) equation and (extended) Painlev\'e IV solitons for the Boussinesq equation.

Abstract: One of the oldest methods for constructing integrable Hamiltonian systems, proposed by Jacobi, recently is being presented as a novel St\"{a}ckel lift construction related with Haantjes geometry. It may cause some confusion.
