DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GEOTOP-A/18/
 ">Is Trivial Knot Really So Trivial?</a>\nby Alexander Grosberg (NYU - USA
 ) as part of GEOTOP-A seminar\n\n\nAbstract\nWhile topological ideas are w
 idely popular in physics\, topology of classical linear threads of polymer
 s presents steep mathematical and conceptual challenges\, with application
 s in both biopolymers and materials.  I will concentrate on the simplest c
 ase of polymer unknots and review what is known about fluctuations and sta
 tistical mechanics of such objects based mostly on simulations\, experimen
 ts\, and hand-waving theoretical arguments.  Continuing with increasingly 
 sophisticated models and phenomena\, I will review several more recent the
 oretical and experimental achievements\, and conclude with the discussion 
 of a controversial concept of “topological glass”.\n
