I hope you enjoy your time here. Like many of us, I receive e-mails periodically from websites that inform me that classmates or friends or relatives or researchers have searched my name. They may have gotten to a Wikipedia site that was written without my knowledge by an undergraduate at the University of Chicago, or to a research site that holds some of my articles. In this website, I have attempted to render a broader view of the three most salient interests (other than my immediate family) that move and have moved me over the years, both personal and professional: mathematics and mathematics education, including material one would find in my c.v.; genealogy; and music. Links to other websites are as of January 2022 and may not be operable at later dates or in all locations. Comments and suggestions for improvements of this website are welcome. https://www.zalmanusiskin.com/new-page-3 daily 0.75 2022-02-05 https://www.zalmanusiskin.com/published-reviews daily 0.75 2022-02-05 https://www.zalmanusiskin.com/usiskins daily 0.75 2022-02-13 https://www.zalmanusiskin.com/unpublished-papers daily 0.75 2022-02-05 https://www.zalmanusiskin.com/new-page daily 0.75 2022-02-05 https://www.zalmanusiskin.com/grants daily 0.75 2022-02-05 https://www.zalmanusiskin.com/publications-1 daily 0.75 2022-02-11 https://www.zalmanusiskin.com/doctoral-students daily 0.75 2022-02-05 https://www.zalmanusiskin.com/new-page-1 daily 0.75 2022-02-05 https://www.zalmanusiskin.com/presentations-honours daily 0.75 2022-02-05 https://www.zalmanusiskin.com/upcoming-events daily 0.75 2026-04-03 https://www.zalmanusiskin.com/videos-and-films daily 0.75 2022-02-05 https://www.zalmanusiskin.com/jacobsons daily 0.75 2022-02-05 https://www.zalmanusiskin.com/published-articles daily 0.75 2022-02-05 https://images.squarespace-cdn.com/content/v1/61c4f22834d79e42f8e6863f/84e770c7-b8fa-4df2-bbdd-ed895f38c6ce/Untitled12.jpg PUBLISHED ARTICLES -
