Résumé

We define quittable consensus, a natural variation of the consensus problem, where processes have the option to agree on "quit" if failures occur, and we relate this problem to the well-known problem of nonblocking atomic commit. We then determine the weakest failure detectors for these two problems in all environments, regardless of the number of faulty processes.

Option style

In finance, the style or family of an option is the class into which the option falls, usually defined by the dates on which the option may be exercised. The vast majority of options are either European or American (style) options. These options—as well as others where the payoff is calculated similarly—are referred to as "vanilla options". Options where the payoff is calculated differently are categorized as "exotic options". Exotic options can pose challenging problems in valuation and hedging.

Option

En finance, une option est un produit dérivé qui établit un contrat entre un acheteur et un vendeur. L'acheteur de l'option obtient le droit, et non pas l'obligation, d'acheter (call) ou de vendre (put) un actif sous-jacent à un prix fixé à l'avance (strike), pendant un temps donné ou à une date fixée. Ce contrat peut se faire dans une optique de spéculation sur le prix futur de l'actif sous-jacent, ou d'assurance contre une évolution défavorable de ce prix.

Asian option

An Asian option (or average value option) is a special type of option contract. For Asian options, the payoff is determined by the average underlying price over some pre-set period of time. This is different from the case of the usual European option and American option, where the payoff of the option contract depends on the price of the underlying instrument at exercise; Asian options are thus one of the basic forms of exotic options.
