Complexification of a Real Krein Space. Part I
Introduction There is a rather unusual journal called the Journal of Humanistic Mathematics. It aims to provide an open forum for academic and informal discussions of the “human face of mathematics,” focusing on aesthetic, cultural, historical, literary, pedagogical, philosophical, psychological, … Continue reading
Fundamental Symmetries in Minkowski Krein Space
It is always good to have at least one example. I am reading the Preface to A Course in Functional Analysis by John B. Conway (Springer, 1985), where the author notes: Historically, mathematics has gone from the particular to the general—not the … Continue reading
Krein spaces – first steps
It was the summer of 1964 (15 June–15 July). The small village of Katsiveli, in the Yalta region of Crimea, hosted the Second Summer School of Mathematics organized by the Ukrainian Academy of Sciences. Second Summer School of Mathematics, Katsiveli, … Continue reading
