As part the R.W. Yeagy Colloquium Series, Mr. Quinn Morris will be talking about “FROM THEORY TO PRACTICE: BOUNDARY VALUE PROBLEMS AND *PROKELISIA ARGINATA ”* at 2:30 PM on Monday February 27

^{th}in Math 357.

Abstract: In a first course in ordinary differential equations, one often treats initial value problems and is able to show existence & uniqueness of solutions when f is “nice”. In this talk, we will instead consider boundary value problems, and observe that even for very “nice” functions f, existence and uniqueness is a much more complicated question. In the second half of the talk, we will discuss some boundary value problems arising from population models with density dependent dispersal on the boundary. The NSF-funded study of these models is on-going work with a group of undergraduates, graduate students, and faculty at three universities. (flyer in PDF form)
