This book is a treasured documentation of the talks given at the meeting authors have organized. Gordon Semenoff has left a legacy of influence in the theoretical physics community in Canada and globally. His contributions to the field are far-reaching and significant. He is held in the highest esteem by world-renowned. Authors are celebrating his 70th birthday with this conference. All of the speakers who will be contributing to the volume will have been his collaborators or his close colleagues.
