On the 3-kings and 4-kings in multipartite tournaments
Koh and Tan gave a sufficient condition for a 3-partite tournament to have at least one 3-king in [K.M. Koh, B.P. Tan, Kings in multipartite tournaments, Discrete Math. 147 (1995) 171–183, Theorem 2]. In Theorem 1 of this paper, we extend this result to n-partite tournaments, where n 3. In [K.M. Koh, B.P. Tan, Number of 4-kings in bipartite tournaments with no 3-kings, Discrete Math. 154 (1996)...
متن کاملRainfall and Dragon-Kings
Previous studies have found broad distributions, resembling power laws for different measures of the size of rainfall events. We investigate the large-event tail of these distributions and find in one measure that tropical cyclones account for a large proportion of the very largest events outside the scaling regime, i.e., beyond the cutoff of the power law. Tropical cyclones are sufficiently ra...
متن کاملThe Complexity of Kings
A king in a directed graph is a node from which each node in the graph can be reached via paths of length at most two. There is a broad literature on tournaments (completely oriented digraphs), and it has been known for more than half a century that all tournaments have at least one king [Lan53]. Recently, kings have proven useful in theoretical computer science, in particular in the study of t...
متن کامل14 - Of Kings and Capitals
ALAN L. KOLATA Cities, and the larger political formations within which they are embedded, are dynamic congeries of political, economic, and social institutions that are shaped and reshaped by historical circumstance. This dynamism and mutability in the face of exogenou-s forces might suggest the impossibility of a coherent, general theory about the forms and forces of urban transformation of t...
متن کاملOn the Domination of Kings
In this paper, we consider counting the number of ways to place kings on an k × n chessboard, such that every square is dominated by a king. Let f(k, n) be the number of dominating configurations. We consider the asymptotic behavior of the function f(k, n).
