Abstract. Let H be a permutation group on a set Λ, which is permutationally isomorphic to a finite alternating or symmetric group An or Sn acting on the k-element subsets of points from {1, . . . , n}, for some arbitrary but fixed k. Suppose moreover that no isomorphism with this action is known. We show that key elements of H needed to construct such an isomorphism φ, such as those whose image...

In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling to spend that much, and who is ready to use a hedging strategy which succeeds with high probability.

in order to investigate effective factors on bread waste and determine effect genial of each factor on probability of being each family in three categories of low-medium, high and extra high bread waste, the order logit model and the 352 families data from mashad city were taken in use. the samples have been selected using a simple random sampling method. the survey of marginal effect in order ...

We revise cosmological mass bounds on hadronic axions in low-reheating scenarios, with a reheating temperature $T_{\rm RH}~\le 100$ MeV, light of the latest observations. In this situation, neutrino decoupling would be unaffected, while thermal axion relic abundance is suppressed. Moreover, are colder so that their possibly loosened. As consequence these two facts, limits relaxed. Using state-o...

in recent years, human activities has resulted increases in atmospheric carbon dioxide (co2) concentration. increase in [co2] has caused global warming and climate change. the aim of this study was to assess potential climate change impact on production for one of the most important varieties of wheat (chamran) in ahvaz region. for this purpose, thirteen aogcm models and two greenhouse gases em...
