This is the screencast of a seminar talk I gave in May 2016, the slides for which can be found here: therisingsea.org/notes/talk-ainf-minimal.pdf.
Abstract: After a brief introduction to A-infinity algebras, I state the minimal model theorem for DG-algebras and give an example coming from singularity theory, namely, the DG-endomorphism algebra of the generator of the category of matrix factorisations of an isolated hypersurface singularity. This talk ended with the definition of this DG-algebra (due to Dyckerhoff), and presumably will continue at some point with the details of the minimal model theorem in this case and the associated topological Feynman diagrams.
Notes: The audio was recorded during the blackboard talk, with the video created afterwards using an iPad Pro and the screen mirroring software Reflector 2 (so I guess this is technically a "boardcast" rather than a screencast). The two were edited together with Camtasia for Mac.
