International workshop celebrates Hadamard matrices
In celebration of the fifth year anniversary of the publication of Hadamard Matrices and their Applications by Princeton University Press, RMIT University hosted an international workshop celebrating the book and its author, Professor Kathy Horadam.
Professor Kathy Horadam explaining the cocycles and their equivalent classes.
Winthrop Professor and ARC Federation Fellow Cheryl Prager opened the highly specialised mathematics conference, which brought together 38 participants, including researchers from the USA, Canada, Spain, Hungary, Ireland and New Zealand.
Professor Prager praised Professor Horadam as a woman in mathematics par excellence and a great role model for young mathematicians in Australia.
In her talk, Professor Horadam spoke of the need to work on the “hard” problems, and remembered the late Dr Warwick de Launey, who co-founded the area of cocyclic Hadamard matrices with her.
Event organiser, Dr Asha Rao said that the success of the workshop was reflective of the resurgence of interest in Hadamard matrices and the valuable contribution of Professor Horadam.
“It was inspiring to have so many participants attend such an exclusive workshop and it was an outstanding success,” Dr Rao said.
The workshop explored the area of Design theory, a branch of combinatorial mathematics.
Support of the Australian Mathematical Sciences Institute (AMSI) enabled the organisers to partly fund the expenses of a number of attendees.
Examples of Warwick de Launey’s art were shown throughout the workshop, illustrating the often hidden, artistic side of mathematics.
