Jens Lieberum [1]
Jens Lieberum,
a German topologist, chess player, and as Amazons programmer author of Amazong,
two times Gold medal winner of the Computer Olympiad 2002 and 2003.
Jens Lieberum received his Ph.D. in mathematics in 1998 in the field of Knot theory on the topic of Vassiliev invariants [2] at Louis Pasteur University, Strasbourg, France, under supervision of Christian Kassel.
He further researched and published in that field of Knot invariants and Knot polynomial on Quantum invariant,
Quasi-bialgebra and Lie superalgebra,
HOMFLY polynomial, Kauffman polynomial [3] and Alexander polynomial [4],
and the Skein relation, publications categorized by arXiv under Quantum algebra.
