WebOne of the earliest sufficiency conditions is due to Dirac [2] and is based on the intuitive idea that if a given graph contains “enough” lines then it must be Hamiltonian. Similar but more sophisticated theorems have been proved by Ore [3], P&a [4], Bondy [5], Nash-Williams [6], Chvatal [7], and Woodall [8]. WebIn the present article, we establish relation-theoretic fixed point theorems in a Banach space, satisfying the Opial condition, using the R-Krasnoselskii sequence. We observe that graphical versions (Fixed Point Theory Appl. 2015:49 (2015) 6 pp.) and order-theoretic versions (Fixed Point Theory Appl. 2015:110 (2015) 7 pp.) of such results can be extended … rkw inspirationsboxWebaudience a primer on how to interpret graphs in more abstract terms using only linear algebra by proving theorems involving eigenvalues, matrices, and other concepts.
