DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CRMDS/8/">Le
 avitt path algebra via the singularity category of a radical-square-zero a
 lgebra</a>\nby Xiao-Wu Chen (Hefei) as part of Western Sydney University A
 bend Seminars\n\n\nAbstract\nWe will recall some previous work primarily b
 y Paul Smith\, and show that the Leavitt path algebra \nis closely related
  to the singularity category of a finite dimensional radical-square-zero a
 lgebra. Recently\, we apply such a link to confirm Keller's conjecture for
  a radical-square-zero algebra. More precisely\, we prove that for such an
  algebra\, the singular Hochschild cochain complex is B_\\infinity-isomorp
 hic to the Hochschild cochain complex of the dg singularity category. This
  is based on a joint work with Huanhuan Li and Zhengfang Wang.\n
