In this paper, we take an axiomatic approach to characterize insurance prices in a competitive market setting. We present four axioms to describe the behavior of market insurance prices. From these axioms it follows that the price of an insurance risk has a Choquet integral representation with respect to a distorted probability (Yaari, 1987). We propose an additional axiom for reducing compound...

We answer the following question: When does a k-uniform family generated by some rank t element in the function lattice have maximum size among all k-uniform t-intersecting families?

Treewidth is an important and well-known graph parameter that measures the complexity of a graph. The Kneser graph Kneser(n, k) is the graph with vertex set ( [n] k ) , such that two vertices are adjacent if they are disjoint. We determine, for large values of n with respect to k, the exact treewidth of the Kneser graph. In the process of doing so, we also prove a strengthening of the Erdős-Ko-...

as discussed in the main text. Following Bayes rule, p res (kr) is then the sum of the product of the probabilities that a node in the extended residual network has degree kr given that it had original degree ko , (pres(kr|ko)), the probability that the node of original degree ko was uninfected in the rst epidemic, (ηko), and the probability that the node had original degree ko , (pko) . In a s...

A result on finite abelian groups is first proved and then used to solve problems in finite fields. Particularly, all finite fields that have normal bases generated by general Gauss periods are characterized and it is shown how to find normal bases of low complexity. Dedicated to Professor Chao Ko on his 90th birthday.

A nonuniform class called here Full-P/log, due to Ko, is studied. It corresponds to polynomial time with logarithmically long advice. Its importance lies in the structural properties it enjoys, more interesting than those of the alternative class P/log; speciically, its introduction was motivated by the need of a logarithmic advice class closed under polynomial-time deterministic reductions. Se...

renewable natural resources are the wealth that not only belongs to the currentgeneration but also to future generations. diversity in rangeland user viewpoints and policymakers has caused these lands to face some damages. this study was conducted to compareviewpoints of ordinary members as rangeland users, and board of directors as executives ofmanagement plans. statistical population of the s...
