Velimirović (University of Niš) as part of GEOTOP-A semina r\n\nInteractive livestream: https://us02web.zoom.us/j/82372719493?pwd=x5q 4FSLS5LZAWCFqfNkTKhUQtHpaJJ.1\n\nAbstract\nEnergies of geometric objects u nder infinitesimal deformation (or bending) measure how curvature-based sh ape functionals—like Willmore or torsional energy—change. Because infi nitesimal bending preserves intrinsic geometry (metric and Gaussian curvat ure).\n\nThe relationship between the shape of geometric objects and their energies is a fundamental concept that explains their properties and beha vior in various fields\, including nature\, engineering\, and architecture . Energy-minimizing shapes\, like spheres for droplets or spherical cells are common because they are efficient and stable. Applications range from designing energy-absorbing thin-walled structures to understanding the pro perties\, demonstrating the universal principle that form follows function and energy optimization.\n\nIn this talk we will consider specially shape and energy under infinitesimal bending.\n\nReference\nShape and Energies of Geometric Objects\nLouis H Kauffman (University of Illinois at Chicago\ , USA) Ljubica S Velimirović (University of Niš\, Serbia)\, Marija S Naj danović (University of Priština in Kosovska Mitrovica\, Serbia)\, and Sv etozar R Rančić (University of Niš\, Serbia)\nSeries on Knots and Every thing: Volume 80\nWorld Scientific\, April 2026\n LOCATION:https://researchseminars.org/talk/GEOTOP-A/126/ URL:https://us02web.zoom.us/j/82372719493?pwd=x5q4FSLS5LZAWCFqfNkTKhUQtHpa JJ.1 END:VEVENT END:VCALENDAR
