## Lehman Publishes Book in Dolciani Series

Larry Lehman, Professor of Mathematics, has had his book, *Quadratic Number Theory: An Invitation to Algebraic Methods in the Higher Arithmetic,* published by MAA Press, an imprint of the American Mathematical Society. The book appears in the Dolciani Mathematical Expositions series, devoted to “mathematical elegance and ingenuity” in texts intended for undergraduate math majors. It features innovations in notation developed during several directed studies and topics courses in algebraic number theory led by Prof. Lehman at the University of Mary Washington.

## UMW Students Win Math Competition

UMW students Riley Anderson and Makenzie Clower, accompanied by Assistant Professor of Mathematics Jeb Collins, delivered outstanding performances at the Joint Mathematics Meetings in Baltimore earlier this month.

Anderson and Clower won the Radical Dash, a group competition that asks participants to answer math questions through social media, taking home a year subscription to the mathematics software Maple and a textbook. The students also presented at the Mathematical Association of America’s Undergraduate Students Poster Session.

“This conference is a great opportunity for students to see the wider mathematical world, to meet other students from different universities and to hear talks about research done in the field,” Collins said.
