A Congruence modulo Four for Real Schubert Calculus with Isotropic Flags
نویسندگان
چکیده
We previously obtained a congruence modulo four for the number of real solutions to many Schubert problems on a square Grassmannian given by osculating flags. Here, we consider Schubert problems given by more general isotropic flags, and prove this congruence modulo four for the largest class of Schubert problems that could be expected to exhibit this congruence.

A Congruence modulo Four in Real Schubert Calculus
We establish a congruence modulo four in the real Schubert calculus on the Grassmannian of m-planes in 2m-space. This congruence holds for fibers of the Wronski map and a generalization to what we call symmetric Schubert problems. This strengthens the usual congruence modulo two for numbers of real solutions to geometric problems. It also gives examples of geometric problems given by fibers of ...

We describe a large-scale computational experiment studying structure in the numbers of real solutions to osculating instances of Schubert problems. This investigation uncovered Schubert problems whose computed numbers of real solutions variously exhibit nontrivial upper bounds, lower bounds, gaps, and a congruence modulo four. We present a family of Schubert problems, one in each Grassmannian,...

During the last decade, CCS has been extended in diierent directions, among them priority and real time. One of the most satisfactory results for CCS is Milner's complete proof system for observational congruence 31]. Observational congruence is fair in the sense that it is possible to escape divergence, reeected by the axiom recX:(:X + P) = recX:::P. In this paper we discuss observational cong...
متن کاملRestriction Varieties and Geometric Branching Rules
This paper develops a new method for studying the cohomology of orthogonal flag varieties. Restriction varieties are subvarieties of orthogonal flag varieties defined by rank conditions with respect to (not necessarily isotropic) flags. They interpolate between Schubert varieties in orthogonal flag varieties and the restrictions of general Schubert varieties in ordinary flag varieties. We give ...
