Department of Mathematics & Computer Science
PROBLEM. ANALYSIS. SOLUTION.
Our computer science, mathematics and statistics faculty and instructors are top of the line, with credentials to rival other universities in and outside of Canada.
We offer Bachelor of Science undergraduate degrees in Applied Statistics, Computer Science and Mathematics. Both Master's and Doctoral levels of study are also available. Department faculty are currently working with students studying at each of these levels, many of whom are graduate students from around the world. Learn more about our majors and minors.
Undergraduate students may have opportunities to do research projects with our faculty, using modern facilities, for hands-on experience. Several department faculty have independent research programmes supported by agencies such as NSERC and IBM Canada, and at times, there may be a collaboration with other disciplines.
During this unique time in the world, the University of Lethbridge may be a bit restrictive for personal visits, so please take the time to "meet" our faculty and instructors via the buttons directly below. We think you'll see the Department of Mathematics & Computer Science offers a wide range of topics in each of our disciplines, and we're confident you will find something to appeal to your intellectual interests.

Number Theory & Combinatorics Seminar
GUEST: Paul Peringuey - UNBC
Topic: On the exceptional set for sums of two totients
Date: Monday, October 26, 2026
Location: M1060
Time: 12:00 - 1:00 pm
We prove that all but $O(X^{3/5} (\log X)^9)$ even integers up to $X$ are sums of two totients. In fact, we prove the stronger statement that all but $O(X^{3/5} (\log X)^9)$ odd integers up to $X$ are the sum of a prime and a totient. The gain over the Goldbach case comes from replacing one binary problem by a family of them, $p_1 + 2^j p_2 = n + 2^j$, of which only a bounded number can fail simultaneously. We follow Pintz's treatment of sums of three primes with a bounded third prime. This is joint work with Alia Hamieh and Stanley Yao Xiao.
