The Gorenstein and complete intersection properties of associated graded rings
William Heinzer, Mee-Kyoung Kim, Bernd Ulrich
Let I be an m-primary ideal of a Noetherian local ring (R,m). We consider the Gorenstein and complete intersection properties of the associated graded ring G(I) and the fiber cone…
Theorems of Barth-Lefschetz type on Kaehler manifolds of non-negative bisectional curvature
Meeyoung Kim, Jon Wolfson
Theorems of Barth-Lefschetz type describe restrictions on the topology of varieties of small codimension. R. Schoen and J. Wolfson, using Morse theory on a path space, have describ…
Zero Assignment, Pole Placement and Matrix Extension Problems: A Common Point of View
Meeyoung Kim, Joachim Rosenthal, Xiaochang Alex Wang
The paper studies a general inverse eigenvalue problem which contains as special cases many well studied pole placement and matrix extension problems. It is shown that the studied…
On branched coverings of some homogeneous spaces
Meeyoung Kim, Laurent Manivel
We study nonsingular branched coverings of a homogeneous space X. There is a vector bundle associated with such a covering which was conjectured by O. Debarre to be ample when the…
