Relative Bott–Samelson Varieties

نویسندگان

چکیده

We prove that, defined with respect to versal flags, the product of two relative Bott–Samelson varieties over a flag bundle is resolution singularities Richardson variety. This result generalizes Brion’s setting. As an application, this gives singularities, modular interpretation, for Brill–Noether variety imposed ramification on twice-marked elliptic curves.

Relative Support Varieties

We define relative support varieties with respect to some fixed module over a finite dimensional algebra. These varieties share many of the standard properties of classical support varieties. Moreover, when introducing finite generation conditions on cohomology, we show that relative support varieties contain homological information on the modules involved. As an application, we provide a new c...

The Varieties of Uterine Neoplasms and Their Relative Frequency

Uterine tumours are of great interest to the surgeon and' pathologist, as well for the frequency of their occurrence as for the important surgical procedures now often undertaken for their removal. It was very different half a century ago,, when but little was known of the pathology of these tumours, and their surgical treatment was limited to the occasional, removal of specimens that projected...

Cohomology of Relative Cellular Spaces and Isotropic Flag Varieties

Let A be a separable algebra (with an involution). The varieties of flags of (isotropic) ideals of A are considered and certain decompositions of these varieties in the category of Chow-correspondences are produced. As a consequence, decompositions in various cohomology theories are obtained.

Relative Topology of Real Algebraic Varieties in Their Complexifications

We investigate, for a given smooth closed manifold M , the existence of an algebraic model X for M (i.e., a nonsingular real algebraic variety diffeomorphic to M) such that some nonsingular projective complexification i : X → XC of X admits a retraction r : XC → X. If such an X exists, we show that M must be formal in the sense of Sullivan’s minimal models, and that all rational Massey products...

Relative Chow-Künneth decompositions for conic bundles and Prym varieties

We construct a relative Chow-Künneth decomposition for a conic bundle over a surface such that the middle projector gives the Prym variety of the associated double covering of the discriminant of the conic bundle. This gives a refinement (up to an isogeny) of Beauville’s theorem on the relation between the intermediate Jacobian of the conic bundle and the Prym variety of the double covering.
