The Association for Women in Mathematics: How and Why It Was
Mathematical Communities t’s 2011 and the Association for Women in Mathematics The Association (AWM) is celebrating 40 years of supporting and II promoting female students, teachers, and researchers. It’s a joyous occasion filled with good food, warm for Women conversation, and great mathematics—four plenary lectures and eighteen special sessions. There’s even a song for the conference, titled ‘‘((3 + 1) 9 3 + 1) 9 3 + 1 Anniversary in Mathematics: How of the AWM’’ and sung (robustly!) to the tune of ‘‘This Land is Your Land’’ [ICERM 2011]. The spirit of community and and Why It Was the beautiful mathematics on display during ‘‘40 Years and Counting: AWM’s Celebration of Women in Mathematics’’ are truly a triumph for the organization and for women in Founded, and Why mathematics.

Meanwhile, it was only a few months ago in December that someone bombed a block in Nashville. We are no longer discussing that trauma. Many of these events of recent months and years have been fomented by internet communities that foster racism, sexism, and white male supremacy.

The Crucial Work of the AWM Policy and Advocacy Committee
The Crucial Work of the AWM Policy and Advocacy Committee Gail Letzter and Marie A. Vitulli Abstract This article is a behind-the-scenes look at the work of the Association for Women in Mathematics Policy and Advocacy Committee as seen through the eyes of two recent chairs, the authors of this article, whose time on the committee spans the decade between 2010 and 2020. Major undertakings during our terms included creating and revisiting statements on welcoming environment and harassment, responding to the President’s Council of Advisors on Science and Technology report Engage to Excel, initiating Capitol Hill Visits, and crafting a Diversity and Inclusion Statement. We end with a discussion of some of the future challenges the committee might face. Key words: gender, STEM, advocacy, gender discrimination, sexual harassment, diversity Introduction The Association for Women in Mathematics (henceforth denoted by AWM) is the preeminent professional society supporting women and girls in mathematics in the United States and abroad. The Policy and Advocacy Committee (abbreviated by P&A below) is the AWM committee responsible for creating official AWM statements and policies, as well as responding to events that affect the lives of women and others pursuing mathematics. In many ways, P&A serves as the moral conscience of the organization, figuring out the best way to address thorny concerns and difficult situations. However, the work of P&A isn’t always glamorous—in fact, it rarely is. Instead, there are details that must be completed, conflicting perspectives that need to be navigated, complicated processes that have to be evaluated to see if they are suitable for the AWM, and questions that might require legal advice. -
Spectral Graph Theory to Appear in Handbook of Linear Algebra, Second Edition, CCR Press
Spectral Graph Theory to appear in Handbook of Linear Algebra, second edition, CCR Press Steve Butler∗ Fan Chungy There are many different ways to associate a matrix with a graph (an introduction of which can be found in Chapter 28 on Matrices and Graphs). The focus of spectral graph theory is to examine the eigenvalues (or spectrum) of such a matrix and use them to determine structural properties of the graph; or conversely, given a structural property of the graph determine the nature of the eigenvalues of the matrix. Some of the different matrices we can use for a graph G include the adjacency matrix AG, the (combina- torial) Laplacian matrix LG, the signless Laplacian matrix jLGj, and the normalized Laplacian matrix LG. The eigenvalues of these different matrices can be used to find out different information about the graph. No one matrix is best because each matrix has its own limitations in that there is some property which the matrix cannot always determine (this shows the importance of understanding all the different matrices). In the table below we summarize the four matrices and four different structural properties of a graph and indicate which properties can be determined by the eigenvalues. A \No" answer indicates the existence of two non-isomorphic graphs which have the same spectrum but differ in the indicated structure. Matrix bipartite # components # bipartite components # edges Adjacency | AG Yes No No Yes (combinatorial) Laplacian | LG No Yes No Yes Signless Laplacian | jLGj No No Yes Yes Normalized Laplacian | LG Yes Yes Yes No In this chapter we will introduce the normalized Laplacian and give some basic properties of this matrix and some additional applications of the eigenvalues of graphs. -

During his long tenure at Penn he advised twenty-six PhD students and won additional awards, including the Christian and Mary Lindback Award for excellence in undergraduate teaching. Other professional honors and awards included a Guggenheim Fellow- ship in 1973–74 and the Euler Medal, awarded in 2002 by the Institute for Combinatorics and its Applications. Herbert Wilf’s mathematical career can be divided into three main phases. First was numerical analysis, in which he did his PhD dissertation Photo courtesy of Ruth Wilf.
