ESM-2009 investigates the history of the idea of equivalence relation by using a variational approach; that is an investigation of the variation in the ways that some prominent mathematicians of the past have tackled certain situations that from the vantage point of today’s mathematics embody the idea of equivalence relation. The main result of the paper is given in the title! I called the approach used for the study “historical variations“, having in mind that one day I am going to use the same method to study the history of other mathematical concepts.
