We thank the CRM and ISM who supported the visit of Kędra in Montreal. Kędra also thanks the Max Planck Institute for Mathematics for supporting his visit in Bonn. Part of this work has been done during Brandenbursky’s stay at IHES and CRM. We wish to express his gratitude to both institutes. Brandenbursky was supported by CRM-ISM fellowship and NSF grant No. 1002477. This work has been done during Shelukhin’s stay in CRM, ICJ Lyon 1, Institut Mittag Leffler, and IAS. He thanks these institutions for their warm hospitality.
