WebMoreover, Kneser conjectured that k + 2 is the least possible number of classes in such a valid partition. This problem remained open for over twenty years until L. Lovasz [5] showed, using methods from algebraic topology, that Kneser's conjecture was true. Within weeks of learning of Lovasz's proof, I. Bairany [1] produced a very short proof WebSep 12, 2024 · In an earlier paper, the present authors (2015) introduced the altermatic number of graphs and used Tucker’s lemma, an equivalent combinatorial version of the Borsuk–Ulam theorem, to prove that the altermatic number is a lower bound for chromatic number. A matching Kneser graph is a graph whose vertex set consists of all matchings …

WebFurther, all Kneser graphs with determining number 2, 3 or 4 were provided. The main tools used in Boutin (2006) to find determining sets or to bound the determining number of Kneser graphs are based on characteristic matrices and vertex orbits. This paper contains two main results. In Section 2, we compute the determining number of all Kneser ... WebIna Garten, who turns 74 on February 2, and husband Jeffrey have been married for 53 years.
