2021 Combinatorics Workshop, Day 3 (Dec. 22, 2021)
On July 6, 2021,
Suil O (오수일) from SUNY Korea gave a talk at the Discrete Math Seminar on upper bounds of certain eigenvalues to guarantee the existence of an even or odd [a,b]-factor in h-edge-connected r-regular graphs. The title of his talk was “ Eigenvalues and [a, b]-factors in regular graphs“.
On June 19, 2019, Suil O (오수일) from SUNY Korea, Incheon presented his work on an upper bound of the third largest eigenvalue of a connected r-regular graph to have an odd (1,b)-factor. The title of his talk was “An odd [1,b]-factor in regular graphs from eigenvalues”.
