Events
The Department of Mathematics sponsors a regular colloquium that hosts several talks by
external speakers every year and a general faculty seminar for talks by faculty and
students. Seminars are listed below after the colloquia.
Mathematics Colloquium
On Thursday, April 24, 2025, , Assistant Professor of Mathematics Education at CalState - San Bernardino, will present a virtual colloquium lecture on Middle school students鈥� meanings of points from quantitative and covariational reasoning perspectives.
Abstract: In this talk we will discuss students鈥� meanings of points when graphing relationships between quantities in dynamic, experiential contexts. Using data from teaching experiments with middle-grade students, I will illustrate and discuss various meanings, highlighting key differences in them. Two main types of meanings emerged from the data: iconic and quantitative. I will describe four distinct meanings: (i) iconic and transformed iconic translations (where a point represents an object/location), (ii) non-united points (where a point represents a single quantity鈥檚 magnitude), (iii) spatial-quantitative multiplicative objects (where a point is an object/location with quantitative properties), and (iv) quantitative multiplicative objects in conventional and non-conventional planes (where a point represents two quantities鈥� magnitudes). We will conclude with a discussion of the implications of these meanings for research, teaching, and curriculum development.
On Friday, April 25, 2025, , Professor of Mathematics at Kingsborough Community College (CUNY), will present a colloquium lecture on Defining connected components.
Abstract: Suppose \( X \) is a subset of some Cartesian power of the real numbers which has
a 鈥渟imple description.鈥� It is reasonable to ask if the topological components of \(X\)
have equally simple descriptions. If 鈥渟imple description鈥� is taken to mean 鈥渄efinable
by a simple formula of first order logic鈥�, the answer, surprisingly, is no. We show
that for some \(X\) defined by very simple formulas, describing \(X\)鈥檚 components
necessitates an extremely high level of complexity.
This is joint work with Miller, Savatovsky, and Thamrongthanyalak.
