Tushar Das

Tushar Das, Mathematics & Statistics, authored the article "Exact dimension functions of the prime continued fraction Cantor set" in Ergodic Theory and Dynamical Systems published on Monday, May 5 by Cambridge University Press. In joint work with David Simmons (York), we prove that the Hausdorff measure of the prime Cantor set, which comprises the irrationals whose continued fraction entries are prime numbers, cannot be finite and positive with respect to any sufficiently regular gauges, thus negatively answering questions of Mauldin and Urbański (1999) and Mauldin (2013). By contrast, assuming a conjecture on prime gaps that extends the Cramér–Granville heuristics, we prove that the packing measure of the conformal measure on the prime Cantor set is positive and finite with respect to the gauge 𝜓(𝑟)=𝑟^𝛿 log^(−2𝛿)log(1/𝑟), where 𝛿 is the fractal dimension of the prime Cantor set.

Joshua Hertel

Joshua Hertel, Mathematics & Statistics, presented "Mathematics Teacher Educators Rethinking Grading: Examining Alternative Approaches" at the Twenty-Ninth Annual Conference of the Association of Mathematics Teacher Educators on Feb. 8 in Reno, NV.

Submitted on: Mar. 6

Karl Kattchee

Karl Kattchee, Mathematics & Statistics, organized the Special Session on Math and the Arts at the annual Joint Mathematics Meetings (JMM), Jan. 8-11 in Seattle, WA.

Submitted on: Feb. 3

Susan Kelly

Susan Kelly, Mathematics & Statistics, authored the book "Striving for the Limit: Euphemia Lofton Haynes's Fight for Education" and was accepted for publication by 619 Wreath. Haynes was the first African American woman to earn a Ph.D. in mathematics and a major catalyst for the Hobson v. Hanson court case that ruled de facto school segregation unconstitutional. This story was written for a multigenerational audience. Much of the archive materials used for the book was collected and used for a paper authored with former UWL students Carly Shinners and Katherine (Zoroufy) Wagner.
