Paper by O’Brien Published in British Journal of Radiology

Liam O’Brien, professor of mathematics and statistics, coauthored a paper recently published in the British Journal of Radiology titled “Linear Mixed-effects models for estimation of pulmonary metastasis growth rate: implications for CT surveillance in patients with sarcoma.” Their work advances the field by showing that “CT surveillance intervals for pulmonary metastases can be estimated based on metastasis...

O’Brien and O’Connor ’96 Publish Paper in Journal of Maternal-Fetal & Neonatal Medicine

Professor of Mathematics and Statistics Liam O’Brien and Alane O’Connor ’96 have coauthored a paper published in the Journal of Maternal-Fetal & Neonatal Medicine. Titled “Implications of perinatal buprenorphine exposure on infant head circumference at birth,” their research shows that “head circumference in infants exposed to buprenorphine during pregnancy was not significantly different from national norms for...

Taylor Paper on Knots Published in Journal of Topology

Associate Professor of Mathematics Scott Taylor has published a paper in the Journal of Topology titled “Distortion and the bridge distance of knots.” In the study, the coauthors relate the rigid geometric properties of a knot to its more flexible topological properties. A more rigorous explanation of their work is found in the paper’s abstract:  “We extend techniques...

Scott Taylor Publishes Paper in American Mathematical Monthly

Scott Taylor, associate professor of mathematics, cowrote the paper “Two More Proofs that the Kinoshita Graph is Knotted” published in the American Mathematical Monthly. According to the abstract, “The Kinoshita graph is a particular embedding in the 3-sphere of a graph with three edges, two vertices, and no loops. It has the remarkable property that although the...

Gouvêa Reviews Two Books for MAA

Fernando Gouvêa, Colby’s Carter Professor of Mathematics, recently reviewed two books for the Mathematical Association of America. Linear Algebra I, a textbook for both undergraduates in need of advanced material with full proofs and graduate students “in need of a deeper and more complete introduction to linear algebra.” Gouvêa concludes that “a course based on this book...

Taylor Coauthors Paper Published in Algebraic & Geometric Topology

Associate Professor of Mathematics Scott Taylor has coauthored a paper titled “Thin position for knots, links, and graphs in 3-manifolds,” which appeared in volume 18, issue 3 of Algebraic & Geometric Topology. The paper develops a new way of looking at knotted one-dimensional objects in three-dimensional spaces.

Taylor and Collaborators Receive SQuaRE Grant from American Institute of Mathematics

Associate Professor of Mathematics Scott Taylor and four collaborators are the recipients of a SQuaRE grant from the American Institute of Mathematics (AIM) to study the unknotting of spatial graphs. The grant will fund travel to AIM headquarters for a week in 2019. Spatial graphs are networks of nodes and connections positioned, often in knotted ways,...

Gouvêa Reviews Physics from Symmetry for MMA

Fernando Gouvêa, Colby’s Carter Professor of Mathematics, reviewed the textbook Physics from Symmetry for the Mathematical Association of America. Gouvêa, an applied mathematician, tries to read physics but is “generally dissatisfied with what [he] found. So it was with great anticipation that I read Physics from Symmetry, where the author attempts, as the title indicates, to derive much of physics from...

Livshits and Hews ’17 Publish in Electronic Journal of Linear Algebra

Professor of Mathematics Leo Livshits and Joshua Hews ’17 have published an original research article in the Electronic Journal of Linear Algebra. Titled “Groups of Matrices That Act Monopotently” the paper deals with the properties of the eigenvalues of a complex matrix, which are complex numbers associated with the matrix that capture some essential information about its...
