**Course description:**This course explores matrix positivity and operations that preserve it. These involve fundamental questions that have been extensively studied over the past century, and are still being studied in the mathematics literature, including with additional motivation from modern applications to high-dimensional covariance estimation. The course will bring together techniques from different areas: analysis, linear algebra, combinatorics, and symmetric functions.**Meetings:**Tue Thu 3:30 – 5 pm, Mathematics Lecture Hall LH-3**Pre-requisites:**A course in linear algebra, and a course in calculus/real analysis.**Handout/syllabus:**See this link (most/all of the topics should get discussed, though not in the order in the link).**Course notes:**Click on this link for the course notes.**Homework assignments**
