Advanced Lectures in Mathematicstman (1908-1944); however, a first comparative analysis attests to the variety of meanings, uses and functions that he ascribes to the very notion of duality. Let us give a first example: Lautman speaks of duality when two points of view, sometimes distinct, sometimes opposed, sometimes complementar

Hans-Joachim Kabitz,Rolf Dembinskiname is related to the history of at least two such phenomena, namely adjoint (or dual) operators in functional analysis, and the result known as Stone duality in the theory of Boolean algebras. Note that the two phenomena, although they both mark the scientific work of the same mathematician, are q
