   Format: MarkdownItexCreated entry [[Hall algebra]] with a list of references and links for now. Related name entries, [[Daniel Huybrechts]], [[Bernhard Keller]], and updates to [[Berntrand Toen]] (and for the heck, [[Bernhard Riemann]]), and to [[contributors to algebraic geometry]].

   Format: MarkdownItexI added the reference to [[Alexander Efimov|Efimov]]'s paper into [[Hall algebra]]. Warning: cohomological Hall algebra of Kontsevich is a new recent construction, essentially different, from previous Toen's derived Hall and its variant, Kontsevich's motivic Hall algebra etc. Pay attention that the coefficients are of quite different nature.
