Title of Talk: The Toeplitz-Silverman Theorem
Abstract: In the first two decades of the twentieth century summability developed from collection of special results used in other parts of analysis into a full-blown field. One of the main points of this transition was a collection of general results that gave conditions for a method to sum every convergent sequence. Papers by Toeplitz, Silverman, Kojima, Schur and others established these theorems. This note will look at the development of these conditions and, as time permits, the reoccurrence of these results in the early day of the "Polish" school of functional analysis.

Title of Talk: The Toeplitz-Silverman Theorem Part II
Abstract: In the first two decades of the twentieth century summability developed from collection of special results used in other parts of analysis into a full-blown field. One of the main points of this transition was a collection of general results that gave conditions for a method to sum every convergent sequence. Part I of this presentation, which was given last spring, laid out the work that led to the general theory. Papers by Toeplitz, Silverman, Kojima, Schur and others established the theory. This note will look at the development of these conditions and, as time permits, the reoccurrence of these results in the early day of the "Polish" school of functional analysis

Title of Talk: Exact Analytical Solutions of a Chemical Oscillator
Abstract: A chemical reaction network (CRN) is a mathematical model used extensively in chemistry with deep connections to ordinary differential equations (ODEs). CRNs have been used to model naturally occurring reactions that are periodic such as the Brusselator and the Oreganator. However, the nonlinearity of the underlying ODEs is often complex and a large amount of research has been devoted to approximating the solutions to these ODEs. Recently, Luca Cardelli defined a CRN that has similar desirable periodic behavior. In this talk we present a general analysis of this CRN including exact analytical solutions to the underlying ODEs. This is joint work with James I. Lathrop. This talk will be accessible to both undergraduate and graduate students.

Title of Talk: Data Reasoning: Changing our General Math Requirement
Abstract: At Loras College, we have had a mathematical modeling requirement in our general education for some time. Traditional courses like college algebra, precalculus, and calculus satisfy the requirement, as do a variety of “math for liberal arts” type courses. Though all of them use data, none of them deeply engage students in reasoning with data. This means we are not really preparing our students to engage with our data-driven world. We have also had an increased demand for statistics, which barely satisfies our math modeling outcomes. So, whether we are sages or fools, we have decided to essentially change our general education math requirement to a statistics requirement. In this talk, we will share our hopes, our steps in this direction, and our concerns so far.

Title of Talk: Iowa Mathematics Pathway Forum
Abstract: This fall, members of the Iowa Department of Education started a statewide conversation with the goal of improving student success in transitioning from high school to college math, with a focus on low income students and underrepresented minorities. This conversation is taking place through a series of monthly online discussions connecting representatives from various professional Iowa math organizations across high schools, community colleges, Regents institutions, and private four-year colleges and universities. As our representative from the Iowa MAA, I will share the background for this initiative as well as our current progress defining challenges and brainstorming solutions. I will also invite discussion and continued brainstorming from the audience.

Title of Talk: What Does It Mean to Have a Vocation in Mathematics?
Abstract: "Vocation" can be a confusing and even divisive word, but at Loras College, we take the term to mean finding your life's purpose or your way of seeking the common good for society. How can mathematics help our students find purpose and meaning in life? Do our students see mathematics as a way of seeking the common good? Do we? How do we cultivate a sense of mathematical vocation in our students? How do we grow in our own mathematical vocation and share it with our students?

Abstract: In this talk I will present some of the activities my students engaged in and compositions they created in the math of music portion of my January-term course at Loras College. We will apply fractals to musical form, modular arithmetic to chords, transposition, and serialism, and function transformations to counterpoint. No musical background is needed for this talk.

Title of Talk: Farey Symbols and subgroups of $SL_2(Z)$
Abstract: The structure of subgroups of SL_2(Z) (2x2 integer coefficient matrices with determinant 1) is important in the study of modular forms. Associated to these subgroups is an object called a Farey Symbol which contains the structure of the group in a very compact form. For instance, from the Farey Symbol one can easily calculate an independent set of generators for the group, a coset decomposition, and determine if the group is congruence. In this talk, I will discuss finite index subgroups of SL_2(Z)$ and the computation and use of Farey Symbols for these subgroups.

Title of Talk: Teaching Mathematical Probability and Statistics with Internet Applications and R
Abstract: Courses in mathematical statistics can use Internet applications and simulation using the R statistical package to enhance the learning experience. Internet material has been developed for introductory probability and statistics courses and for teaching mathematics at the level of calculus. In order to adapt this material to an intermediate undergraduate probability course, it is necessary to select material to use and incorporate it into lecture, homework assignments, and study problems. The R statistical package is a free software package that can be used for simulation, includes functions related to many probability distributions, and can be used to produce nice graphical displays. Using R in a calculus-based probability course requires writing problems for homework assignments, in-class use, and review that make substantial use of simulation and R

Title of Talk: Characterizing Isometries: A Long Running Undergraduate Research Project
Abstract: In 2010, my adviser Aaron Luttman began an undergraduate research project with an honors student at Clarkson University. The goal was to investigate a decomposition for isometries between normed vector spaces; specifically, to prove that the domain of the isometry had to be the direct sum of ``nice'' subspaces. The project ended in 2011 when my adviser (and the student) left academia. I revived the project in 2015 with an honors student here at Iowa State University, and while significant progress was made, we did not fully resolve it. This semester, I am approaching the problem again with a new student. We'll talk about the ins, outs, and what-have-yous of the project, where we currently stand, and the plan going forward.

Abstract: What if I told you that the majority of ideas conveyed in high school geometry classes are thousands of years old? What if I told you that your understanding of geometry was tremendously incomplete? Believe it or not, one can argue that the first true departure from ancient Greek geometry wasn't published until 1826! In this talk, we describe one such departure and its implications. We begin by describing the curvature of a curve, use this to define the curvature of a surface, and conclude by visiting a famous egregious result. This talk even includes snacks!
