چکیده
We study the cohomology of Jacobians and Hilbert schemes points on reduced locally planar curves, which are however allowed to be singular reducible. show that cohomologies all subcurves encoded in fine compactified connected subcurves, via perverse Leray filtration. also prove, along way, a result independent interest, giving sufficient conditions for smoothness total space relative Jacobian family curves.

Hilbert Schemes of Degree Four Curves
In this paper we determine the irreducible components of the Hilbert schemes H4,g of locally Cohen-Macaulay space curves of degree four and arbitrary arithmetic genus g. We show that these Hilbert schemes are connected, in spite of having ∼ g 2 24 irreducible components. For g ≤ −3 we exhibit a component that is disjoint from the component of extremal curves and use this to give a counterexampl...
متن کاملTHREE SCHEMES FOR ACTIVE CONTROL OF THE PLANAR FRAME
Optimal locations of the actuators for frame active control are investigated in this article. The aim is to minimize the structural drifts by employing several actuators. By utilizing genetic algorithm, the appropriate locations of the actuators are determined. They should be placed in locations where they can minimize the maximum structural drift. To explore the capability of the proposed tech...
متن کاملCounting Singular Plane Curves via Hilbert Schemes
Consider the following question. Given a suitable linear series L on a smooth surface S, how many curves in L have a given analytic or topological type of singularity? By “suitable” linear series with respect to a type of singularity, we mean that there are finitely many curves with the singularity in the linear series and their codimension is maximal. Our approach to this question is to expres...
متن کاملAn Inhomogeneous Jarník Type Theorem for Planar Curves
In metric Diophantine approximation there are two main types of approximations: simultaneous and dual for both homogeneous and inhomogeneous settings. The well known measure-theoretic theorems of Khintchine and Jarník are fundamental in these settings. Recently, there has been substantial progress towards establishing a metric theory of Diophantine approximations on manifolds. In particular, bo...
متن کاملStrong convergence theorem for a class of multiple-sets split variational inequality problems in Hilbert spaces
In this paper, we introduce a new iterative algorithm for approximating a common solution of certain class of multiple-sets split variational inequality problems. The sequence of the proposed iterative algorithm is proved to converge strongly in Hilbert spaces. As application, we obtain some strong convergence results for some classes of multiple-sets split convex minimization problems.
