Advanced Computer Algebra for Determinants
Christoph Koutschan, Thotsaporn "Aek" Thanatipanonda
We prove three conjectures concerning the evaluation of determinants, which are related to the counting of plane partitions and rhombus tilings. One of them was posed by George And…
On Kahan's Rules for Determining Branch Cuts
Frédéric Chyzak, James Davenport, Christoph Koutschan +1
In computer algebra there are different ways of approaching the mathematical concept of functions, one of which is by defining them as solutions of differential equations. We compa…
On Two-generated Non-commutative Algebras Subject to the Affine Relation
Christoph Koutschan, Viktor Levandovskyy, Oleksandr Motsak
We consider algebras over a field K, generated by two variables x and y subject to the single relation yx = qxy + ax + by + c for q in K^* and a, b, c in K. We prove, that among su…
