- In mathematics, a
bialgebra over a
field K is a
vector space over K
which is both a
unital ****ociative
algebra and a
counital co****ociative coalgebra...

bialgebra, but does lead to the
concept of a
cofree coalgebra, and a more
complicated one,
which yields a
bialgebra, and can be extended...

bialgebras are a
generalization of
bialgebras: they were
first defined by the
Ukrainian mathematician Vladimir Drinfeld in 1990. A quasi-
bialgebra differs...
- In mathematics, a Lie
bialgebra is the Lie-theoretic case of a
bialgebra: it is a set with a Lie
algebra and a Lie
coalgebra structure which are compatible...

algebra structure, from the
