The 11th annual Leonard C. Sulski Memorial Lecture in Mathematics will be delivered by Professor Frank Farris of Santa Clara (Calif.) University, on Monday, March 22, at 8 p.m., in room 519 of the Hogan Campus Center. His lecture, “The Edge of the Universe: Noneuclidean Wallpaper,” will explore the concept of symmetry in hyperbolic geometry.

Farris, who received his Ph.D. in mathematics from the Massachusetts Institute of Technology in 1981, has been a member of the department of mathematics and computer science at Santa Clara since 1984. Winner of the Trevor Evans Award in 2002 from the Mathematical Association of America (MAA), he was also awarded the David E. Logothetti Teaching Award at Santa Clara University in 1997.

The lecture series is a tribute to Leonard C. Sulski, who taught in the mathematics department at Holy Cross from 1965 until his death in 1991.

Farris’ talk will be preceded by a dinner co-sponsored by the College department of mathematics and computer science and the MAA. For more information, contact Holy Cross mathematics Professor Tom Cecil, by phone, at (508) 793-2719 or, by e-mail, at tcecil@mathcs.holycross.edu.
