It was there that I began a long collaboration with John Walter and met many of the leaders in the field: Brauer, Suzuki, Graham Higman, and Ito .

Ito ay doon na ako nagsimula ng isang mahabang pakikipagtulungan sa John Walter at matugunan marami sa mga lider sa larangan: Brauer, SUZUKI, Graham Higman, at Ito.

Alperin ay paggastos ng taon sa Chicago na sumulat ng kanyang tesis sa Higman, habang ang isang nagtapos na estudyante sa Princeton.
