Edith Viau will present Arrow's original paper, "A Difficulty in the Concept of Social Welfare" (, that first presented his well-known eponymous theorem. From a practical point of view, she will talk about applying Arrow's impossibility theorem to the problem of scheduling meetings.

Arrow's theorem ( is one of those fascinating, counterintuitive results that always comes up when discussing voting, but for some completely different applications, I recommend Ryan O'Donnel's Analysis of Boolean Functions ( [I'll bring a copy of the book to the meetup, too]. I am looking forward to hearing the treatment of this with respect to calendar problems — this seems like a natural fit, and I'd never made the connection before.

This is a joint effort with the Montreal math meetup group: which I invite you all to check out.

Thanks a lot to Lightspeed for hosting us this time!
