History
Kleene algebras were not defined by Kleene; he introduced regular expressions and asked for a complete set of axioms, which would allow derivation of all equations among regular expressions. The problem was first studied by John Horton Conway under the name of regular algebras. The axioms of Kleene algebras solve this problem, as was first shown by Dexter Kozen.

Famous quotes containing the word history:
“The history of the world is none other than the progress of the consciousness of freedom.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“For a transitory enchanted moment man must have held his breath in the presence of this continent, compelled into an aesthetic contemplation he neither understood nor desired, face to face for the last time in history with something commensurate to his capacity for wonder.”
—F. Scott Fitzgerald (1896–1940)
“The only history is a mere question of one’s struggle inside oneself. But that is the joy of it. One need neither discover Americas nor conquer nations, and yet one has as great a work as Columbus or Alexander, to do.”
—D.H. (David Herbert)
