Herbert Howe Lecture Series

The Herbert Howe Lecture Series brings prominent mathematicians and astronomers to DU to promote current research in mathematics and astronomy. The series is named in honor of Herbert Alonzo Howe, a 19th century professor of mathematics and astronomy at the University of Denver and Denver's first astronomer.

This series is jointly hosted by the Department of Mathematics and the Department of Physics and Astronomy in the College of Natural Sciences.

Announcing the 2019 Herbert Howe Lecture

Ramanujan's Lost Notebook in Five Volumes - Reflections presented by George Andrews, PhD

 

Join the math department in Olin 105 on Thursday, May 30 2019 for this distinguished lecture at 4:00 p.m. followed by a reception at 5:00 p.m. in Olin Rotunda.

Abstract: Bruce Berndt and I have recently completed the fifth and final volume on Ramanujan's Lost Notebook. All of Ramanujan's assertions (with perhaps one of two exceptions) have been proved or, in very rare instances, refuted or corrected.

Among these hundreds of formulas there are a number that stand out.  For example, the recent explosion of results on mock theta functions and mock modular forms has it origin in the Lost Notebook.  The "sums-of-tails" phenomenon also arose from the Lost Notebook. This talk will be a personal account of highlights from this project and questions, yet to be answered, that arose from this decades long effort.

About the speaker: Prof. George Andrews is a leading expert in the theory of partitions. He wrote over 250 research and popular articles on q-series, special functions, combinatorics and applications. Prof. Andrews is a member of the National Academy of Sciences, fellow of the American Academy of Arts and Sciences, and a fellow of the American Mathematical Society. He also served as the president of the American Mathematical Society.

    His research is mainly focussed on Geometric Analysis and Mathematical Physics. He is internationally renowned for the Mathai-Quillen formalism in topological field theories, for his work on the Atiyah-Singer index theory and for T-duality in String Theory in a background flux.

     

    2015

    David Aldous 

    Public lecture 
    May 28, 4-5pm, Olin Hall 105 
    Probability, outside the classroom

    Reception 
    May 28, 5-6pm, Olin Rotunda 

    Seminar for experts 
    May 29, 10am, Aspen Hall 018

    David Aldous received his Ph.D. from Cambridge University in 1977. He is a Professor in the Statistics Department at UC Berkeley, Fellow of the Royal Society, and a member of the National Academy of Sciences.

    His research in mathematical probability has covered weak convergence, exchangeability, Markov chain mixing times, continuum random trees, stochastic coalescence and spatial random networks. A central theme in the works of Dr. Aldous is the study of large finite random structures, obtaining asymptotic behavior as the size tends to infinity via consideration of some suitable infinite random structure.

    2017

    Harold Levinson 

    Public lecture 
    Oct 11, 4-5pm, Olin 105
    The Formation of Planets from the Direct Accretion of Pebbles & the Lucy Mission to the Trojan Asteroid

    Dr. Harold (Hal) Levison received his PhD from University of Michigan in 1986 and presently is Institute Scientist at the SouthWest Research Institute in Boulder. His principal research interests include the dynamics of astronomical objects. He is perhaps best known, however, for his work on the early dynamical evolution of the outer Solar System, and is an author of the most comprehensive model to date. Recently, his LUCY proposal was accepted by NASA for a spacecraft visit to the Jupiter Trojan asteroids.

    Paul Hemenway started his astronomical career measuring star positions at the US Naval Observatory. He received his Ph.D. in Astronomy at the University of Virginia in 1974 measuring the positions of radio sources using Very Long Baseline Interferometry. In 1978 he became a founding member of the Hubble Space Telescope (HST) Astrometry Science Team, and used the HST Fine Guidance Sensors to help determine the coordinate system for the HIPPARCOS Astrometry Satellite. Now retired, he contributes to the Physics and Astronomy Department and the Enrichment Program at DU.

    Prior to joining University of Denver in 1993, Dr. Stencel worked at NASA Houston and Greenbelt sites and at NASA Headquarters in Washington DC. He teaches astronomy courses and publishes research in astrophysics.

History

Herbert Howe joined the faculty in 1881 and received his doctorate in May 1884 with a thesis on a novel solution to Kepler's two body problem. He became the first director of the Chamberlin Observatory, a position in which he remained until his death in 1926.

Among his many accomplishments, he is responsible for determining the location of the original Mile High marker at the staircase of the Colorado capitol building in 1909, later replaced with an etched inscription. His measurements were more precise than those of a 1969 survey and only about 3 feet above the modern 2003 plaque.
