Coherent Sheaves, Chern Classes, and Superconnections on Compact Complex-Analytic Manifolds

Posted by klaurent Tokyo

Kavli Affiliate: Alexey Bondal | Summary:We construct a twist-closed enhancement of the category $mathcal D^b_rm coh(X)$, the bounded derived category of complexes of $mathcal O_X$-modules with coherent cohomology, by means of the DG-category of $barpartial$-superconnections. Then we apply the techniques of $barpartial$-superconnections to define Chern classes and Bott-Chern classes of objects in the category, in […]

Electroconvective flow in presence of polyethylene glycol oligomer additives

Posted by klaurent Cornell

Kavli Affiliate: Lynden Archer | Summary:Metal electrodeposition in batteries is fundamentally unstable and affected by different instabilities depending on operating conditions and chemical composition. Particularly at high charging rates, a hydrodynamic instability called electroconvection sets in that aggravates the situation by creating non-uniform ion flux and preferential deposition at the electrode. Here, we experimentally investigate […]
