#### Nonsolvability of elliptic operators in the flat category

###### Martino Fassina (Illinois Math)

Abstract: In 1957 a ground-breaking three-page paper in the Annals marked the birth of CR geometry. There, Hans Lewy gave the first example of a locally non-solvable first-order linear partial differential equation. In this talk I will present a Lewy-type phenomenon for flat functions. That is, smooth functions whose derivatives are all equal to zero at a point. The result is elementary in nature, and no deep analytic background is required to understand this talk. I will describe some of the consequences of the result, with special attention to complex analysis. The talk is based on joint work with Yifei Pan.

4:00 pm in 345 Altgeld Hall,Friday, December 7, 2018

#### Zero-one laws of Erdos–Renyi random graphs

###### Grigory Terlov (UIUC Math)

Abstract: This topic connects Probability theory with Logic. We will define a random graph, talk about why they are interesting in Probability theory, briefly touch on almost sure theories before spending majority of the time discussing various zero-one laws, including zero-one k-laws. This talk should be accessible to people without much experience in either subject.

4:00 pm in 241 Altgeld Hall,Friday, December 7, 2018

#### Topological K-theory and the Hopf Invariant One Problem

###### Elizabeth Tatum (UIUC)

Abstract: I'll define topological k-theory and discuss its application to the Hopf invariant one problem.

#### Changing the “Face” of Mathematics

###### Dr. Candice Price (University of San Diego)

Abstract: African Americans, American Indians/Alaska Natives, and Latinx-- who have historically comprised a minority of the U.S. population-- are growing in size and influence. Currently, while we constitute 30 percent of the U.S. population, by 2050, together we will account for greater than 40 percent of the U.S. population. Yet, these groups are largely underrepresented in the STEM fields---especially mathematics. Lately, there has been a growing discussion around this issue of lack of diversity in science and engineering and its effect on the growth and innovation needed in these disciplines to solve the most complex issues humanity faces. I believe one reason people of color are underrepresented in STEM is that students of color rarely see themselves reflected in the STEM community. My service mission is to support those underrepresented in STEM by creating and supporting programs that increase visibility, amplify the voices of women and people of color in STEM and create networks and community in STEM to provide opportunities to share resources. In this talk, I will describe my path in mathematics through exploration of my involvement in programs that are working towards changing the face of mathematics.
