Selecta I - Research Contributions

This collection showcases the mathematical writings of P. R. Halmos, featuring research publications primarily focused on probability, measure theory, and operator theory, organized chronologically. Key expository papers, including "Ten Problems in Hilbert Space," are included, alongside introductory essays discussing Halmos's contributions to ergodic theory and operator theory. Notably, papers from the mid-1950s on algebraic logic are excluded, having been published separately. The volume highlights Halmos's impact on mathematics through both specialized and popular writings.
