• Speaker: Dr Paul Leopardi, Australian National University
  • Title: New constructions for Hadamard matrices
  • Location: Room V129, Mathematics Building (Callaghan Campus) The University of Newcastle
  • Time and Date: 4:30 pm, Thu, 26th Apr 2012
  • Please note the start time.
  • Abstract:

    The talk will outline some topics associated with constructions for Hadamard matrices, in particular, a relatively simple construction, given by a sum of Kronecker products of ingredient matrices obeying certain conditions. Consideration of the structure of the ingredient matrices leads, on the one hand, to consideration of division algebras and Clifford algebras, and on the other hand, to searching for multisets of {-1,1} ingredient matrices. Structures within the sets of ingredient matrices can make searching more efficent.
