Arithmetically Cohen-macaulay Curves Cut out by Quadrics
Main Question: Let C ⊂ P r = CP r be a smooth arithmetically Cohen-Macaulay curve which is cut out scheme theoretically by quadrics. Is the homogeneous ideal of C necessarily cut out by quadrics? In [4], it was shown that the question has an affirmative answer if r ≤ 5. The purpose of this note is to show that the question has a negative answer (there is a counterexample with r = 7). It is a pl...
متن کاملProper Actions of High-Dimensional Groups on Complex Manifolds
We explicitly classify all pairs (M,G), where M is a connected complex manifold of dimension n ≥ 2 and G is a connected Lie group acting properly and effectively on M by holomorphic transformations and having dimension dG satisfying n 2 + 2 ≤ dG < n 2 + 2n. These results extend – in the complex case – the classical description of manifolds admitting proper actions of groups of sufficiently high...
متن کاملMotion Synthesis on Manifolds in High Dimensional Space
A lot of work has been done on how to reuse motion capture data and minimize the amount of manual work required in obtaining it. Processing and analyzing the input data, which is of a high dimensionality, recognizing the data and generating new motion behavior can be very complicated. Therefore it is necessary to reduce the data dimensions, while preserving the motion features embedded in the d...
متن کاملRigidity of high dimensional graph manifolds
We define the class of high dimensional graph manifolds. These are compact smooth manifolds supporting a decomposition into finitely many pieces, each of which is diffeomorphic to the product of a torus with a finite volume hyperbolic manifold with toric cusps. The various pieces are attached together via affine maps of the boundary tori. We require all the hyperbolic factors in the pieces to h...
متن کاملOn three dimensional stellar manifolds
It is well known that a three dimensional (closed, connected and compact) manifold is obtained by identifying boundary faces from a stellar ball a ⋆ S. The study of S/ ∼, two dimensional stellar sphere S with 2-simplexes identified in pairs leads us to the following conclusion: either a three dimensional manifold is homeomorphic to a sphere or to a stellar ball a⋆S with its boundary 2-simplexes...
