TY - RPRT T1 - Translation and adaptation of Birman's paper "On the theory of self-adjoint extensions of positive definite operators" (1956) Y1 - 2015 A1 - Mikhail Khotyakov A1 - Alessandro Michelangeli AB - This is an accurate translation from Russian and adaptation to the modern mathematical jargon of a classical paper by M. Sh. Birman published in 1956, which is still today central in the theory of self-adjoint extensions of semi-bounded operators, and for which yet no English version was available so far.
