DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PHK-cohomolo
 gy-seminar/142/">Non-regular Lagrangian concordances between Legendrain kn
 ots</a>\nby Roman Golovko (Charles University) as part of Prague-Hradec Kr
 alove seminar Cohomology in algebra\, geometry\, physics and statistics\n\
 nLecture held in the blue lecture room + ZOOM meeting.\n\nAbstract\nFor a 
 while\, it was an open question whether a Lagrangian cobordism with a non-
 empty positive end can be decomposed into a concatenation of elementary pi
 eces: traces of Legendrian isotopies\, isolated standard-unknot births ind
 ucing Lagrangian 0-handle attachments\, and Legendrian surgeries inducing 
 Lagrangian 1-handle attachments. We answer this question negatively. This 
 is joint work with Georgios Dimitroglou Rizell.\n
