Syzygies and singularities of tensor product surfaces of bidegree (2, 1)
Let U ⊆ H(OP1×P1 (2, 1)) be a basepoint free four-dimensional vector space. The sections corresponding to U determine a regular map φU : P1 × P1 −→ P3. We study the associated bigraded ideal IU ⊆ k[s, t;u, v] from the standpoint of commutative algebra, proving that there are exactly six numerical types of possible bigraded minimal free resolution. These resolutions play a key role in determinin...
متن کاملUntrimming: Precise conversion of trimmed-surfaces to tensor-product surfaces
Trimmed B-spline surfaces are very common in the geometric computer aided design (CAD) community due to their capability to represent complex shapes that cannot be modeled with ease using tensor product Bspline and NURBs surfaces. However, in many cases, handling trimmed-surfaces is far more complex than tensor-product (non-trimmed) surfaces. Many algorithms that operate on tensor-product surfa...
متن کاملLinear syzygies and birational combinatorics
Let F be a finite set of monomials of the same degree d ≥ 2 in a polynomial ring R = k[x1, . . . , xn] over an arbitrary field k. We give some necessary and/or sufficient conditions for the birationality of the ring extension k[F ] ⊂ R, where R is the dth Veronese subring of R. One of our results extends to arbitrary characteristic, in the case of rational monomial maps, a previous syzygy-theor...
متن کاملSpecial linear systems and syzygies
LetX be the base locus of a linear system L of hypersurfaces in Pr(C). In this paper it is showed that the existence of linear syzygies for the ideal of X has strong consequences on the fibres of the rational map associated to L. The case of hyperquadrics is particularly addressed. The results are applied to the study of rational maps and to the Perazzo’s map for cubic hypersurfaces.
متن کاملTractability of Tensor Product Linear Operators
This paper deals with the worst case setting for approximating multivariate tensor product linear operators defined over Hilbert spaces. Approximations are obtained by using a number of linear functionals from a given class of information. We consider the three classes of information: the class of all linear functionals, the Fourier class of inner products with respect to given orthonormal elem...
