Speaker:

Dr. Alfonso Castro (Chair, Harvey Mudd College Math Department)

Abstract:

Principles for the existences of critical points will be discussed and applied to the solvability of boundary value problems. Terms such as deformation lemma, mountain pass lemma, Palais-Smale condition, and saddle point principle will be explained.

Colloquium

Speaker:

Dr. Winston Ou (Scripps College)

Abstract:

The theory of the structure of weights, which reached a peak in the 1980 with the eponymous "factorization theorem'' of Peter Jones, is by now no longer young. Yet despite its middle age, it is still capable of some aesthetically satisfying surprises. We will present a brief introduction to the theory and describe how some recent insights have simplified our understanding of the later refinement (Cruz-Uribe-Neugebauer, 1995) of Jones's result to simultaneously incorporate "reverse Hölder'' class information.

Colloquium

Speaker:

Dr. Shawn McMurran (California State University, San Bernardino)

Abstract:

What is the trajectory of a projectile launched into the air? Archimedes, Tartaglia, Galileo, Torricelli, Descartes, Newton and Bernoulli are just a few among the many mathematicians who had investigated this question by the time it caught the attention of Leonhard Euler. Not to mention that his boss at the time was more than a little interested in specific applications of the solution, such as determining the horizontal range of a musket ball with 3/4 inch diameter and an initial velocity of 1700 feet per second when fired at an angle of 45 degrees.

The 18^th century saw significant advances in the analysis of the trajectory of a projectile in air. In the first half of this century, Benjamin Robins, a British mathematician and military engineer, published New Principles of Gunnery, the first book to deal extensively with external ballistics. Robins' work motivated a deeper mathematical analysis of projectile motion and invited ``commentary'' from Euler. In this talk we consider the influence of Robins' work and look at how Euler used it to attack the problem of projectile motion.

Speaker:

Dr. Stacy Brown (Pitzer and Claremont McKenna Colleges)

Abstract:

“Now is a time of great interest in K-12 mathematics education. Student performance, curriculum, and teacher education are the subjects of much scrutiny and debate. Studies of the mathematical knowledge of prospective and practicing U.S. teachers suggest ways to improve their mathematical educations” (Conference Board of the Mathematical Sciences, 2001)

Elementary school teachers are the public face of mathematics. (Phillip Wagreich, Mathematician)

In this talk, I will share findings from studies indicating that we should be concerned about U.S. teachers’, including prospective teachers’, mathematical content knowledge for teaching. Using recent research findings and vignettes from classroom lessons, I will elaborate on the notion of mathematical content knowledge for teaching and illustrate how teaching mathematics, even to young children, may entail more mathematical thinking on the teacher’s behalf than one might expect. I will then consider recent recommendations for the mathematical preparation of teachers and how mathematics departments have enacted these recommendations. In so doing, I hope to convey to the audience the distinct and important contribution that mathematicians are uniquely qualified to make toward the improvement of the mathematics education of teachers and consequently, school age children.

Colloquium

Speaker:

Dr. Michael O'Neill (Claremont McKenna College)

Abstract:

The theory of harmonic measure describes the way in which a random particle in a domain first hits the boundary. It also, and equivalently, gives a description of the boundary behavior of solutions to Laplace's equation in a given, perhaps very complicated, domain.

A brief survey of harmonic measures in the plane and in space will be followed by a discussion of some analogs of classical theorems about exit behavior of Brownian motion in simply connected planar domains to the case of multiply connected planar domains and to some classes of "nice'' domains in three dimensions. There are many interesting open questions in the area and we will try to talk about a few of them. The talk will be accessible to undergraduates.
