The algebraic combinatorial approach for low-rank matrix completion
[OWP-2013-05] (Mathematisches Forschungsinstitut Oberwolfach, 2013-03-14)We propose an algebraic combinatorial framework for the problem of completing partially observed low-rank matrices. We show that the intrinsic properties of the problem, including which entries can be reconstructed, and ... -
Even-homogeneous supermanifolds on the complex projective line
[OWP-2013-02] (Mathematisches Forschungsinstitut Oberwolfach, 2013-03-14)The classification of even-homogeneous complex supermanifolds of dimension 1|m, m<=3, on CP1 up to isomorphism is given. An explicit description of such supermanifolds in terms of local charts and coordinates ... -
Invariants of Closed Braids via Counting Surfaces
[OWP-2012-15] (Mathematisches Forschungsinstitut Oberwolfach, 2012)A Gauss diagram is a simple, combinatorial way to present a link. It is known that any Vassiliev invariant may be obtained from a Gauss diagram formula that involves counting subdiagrams of certain combinatorial types. In ... -
On the autonomous metric on the group of area-preserving diffeomorphisms of the 2-disc
[OWP-2012-16] (Mathematisches Forschungsinstitut Oberwolfach, 2012)Let D2 be the open unit disc in the Euclidean plane and let G:=Diff(D2;area) be the group of smooth compactly supported area-preserving diffeomorphisms of D2. For every natural number k we construct an injective ...
