Nowhere dense subvariety
WebIn topology and algebraic geometry, a generic property is one that holds on a dense open set, or more generally on a residual set, with the dual concept being a nowhere dense set, or more generally a meagre set. There are several natural examples where those notions are not equal. [1] Web23 sep. 2012 · In an infinite-dimensional Hilbert space, every compact subset is nowhere dense. The same holds for infinite-dimensional Banach spaces, non-locally-compact Hausdorff topological groups, and products of infinitely many non-compact Hausdorff topological spaces.

Thus, there is a universal ... WebWe prove that for every polynomial ODE there exists a Carnot group where the trajectories of the ODE lift to abnormal curves. The proof defines an explicit construction to determine a covector for the resulting abnormal curves. Using this method we give new examples of abnormal curves in Carnot groups of high step.

We were somewhat surprised to find the following partial answer to the above question. 1.1. Theorem. Let X be a compact space of ir-weight < k (k > u>). Then there is an x E X such that x E Kfor all closed nowhere dense PK-sets K c X.

WebWe apply ideas from conformal field theory to study symplectic four-manifolds, by using modular functors to “linearise” Lefschetz fibrations. In Chern-Simons theory this leads to the study of parabolic vector bundles of conformal blocks. Motivated by the Hard Lefschetz theorem, we show the bundles of SU(2) conformal blocks associated to Kähler surfaces … top gun 1986 distributionWebAbstract.

Almost every function in C[0, 1] is nowhere differentiate; that is, the nowhere differentiable functions form a prevalent subset of C[0, 1].
