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.

Topic: Equitable and semi-equitable colourings of combinatorial designs
Date: Monday, April 13
Time: 12:15 - 1:15 pm in M1060
A c-colouring of a combinatorial design is an assignment of colours, chosen from a set of size c, to the points of the design. A c-colouring is equitable if every block of size k contains ⌊k/c⌋ or ⌈k/c⌉ points of each colour. In 2016, Luther and Pike characterized c-colourable balanced incomplete block designs (BIBDs), proving that nontrivial equitable c-colourings exist only for a family of highly restricted parameter sets. By contrast, equitable colourings of cycle designs seem to exist more widely. In this talk, we review known results on equitable colourings and discuss some recent results on equitable colourings of various classes of design. Motivated by the scarcity of equitably-colourable BIBDs, we introduce the concept of a semi-equitable c-colouring, where in each block of size k, one colour which does not appear at all but each other colour appears on ⌊k/(c−1)⌋ or ⌈k/(c−1)⌉ points. Reporting on joint work with William Kellough and David Pike, we give necessary conditions for the existence of semi-equitably colourable BIBDs and present construction methods for such designs using Hadamard matrices, affine planes and twin prime powers.
EVERYONE IS WELCOME!
