<Mikhail Samuilovich Livsic>, also known as <Moshe Livšic>, was a <mathematician> whose work connected <complex analysis> with <linear operator theory>. He studied with <Mark Krein> and developed research on Hermitian operators, the <moment problem> and extensions of operators, later building a research school at Ben-Gurion University.https://mathshistory.st-andrews.ac.uk/Biographies/Livsic/[Biography, doctoral research, operator theory and move to Israel]{ref} A recurring idea in his work was to describe an operator by analytic data rather than only by its action on vectors. Such a viewpoint connects the geometry of an infinite-dimensional space with the behavior of analytic functions, and supplies tools for questions arising in <quantum theory>.
