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.
