purpose the purpose of this study was to describe the body structure and morphological characteristics of tunisian elite handball players, and to determine the effect of these variables on functional and physical performance levels. methods a sample of 42 male handball players (mean age 21.98±3.24 years; training duration 12 years) at international level was submitted to a test battery comprisi...

The thesis is composed of three essays on auction theory. The focus is mainly on the English auction, which is probably the format most commonly used. In the English auction, a bidder can see his opponents’ activity as the price is gradually raised starting from a very low price. When only one bidder is left, such bidder is declared the winner and pays the price at which the last but one bidder...

futures contract is one of the most important derivatives that is used in financial markets in all over the world to buy or sell an asset or commodity in the future. pricing of this tool depends on expected price of asset or commodity at the maturity date. according to this, theoretical futures pricing models try to find this expected price in order to use in the futures contract. so in this ar...

we derive closed formulas for the prices of european options andtheir sensitivities when the underlying asset follows a double-exponentialjump diffusion model, as considered by s. kou in 2002. this author hasderived the option price by making use of double series where each termrequires the computation of a sequence of special functions, such thatthe implementation remains difficult for a large...

1 Wisconsin-Madison, respectively. We would like to thank NSF for providing financial support for this research. Part of this work was done when both authors visited the Bank of Portugal, which provided a stimulating research environment. We also thank seminar participants at several universities for their comments, and John Kennan and Tom Sargent for many useful conversations on these topics.

Let M be a manifold equipped (locally) with a pair of complementary foliations. In Catuogno, da Silva and Ruffino [4], it is shown that, up to a stopping time τ , a stochastic flow of local diffeomorphisms φt in M can be decomposed in diffeomorphisms that preserves this foliations. In this article we present techniques which allow us to extend the time of this decomposition. For this extension,...

The infinite Ramsey theorem is known to be equivalent to the statement ‘for every set X and natural number n, the n-th Turing jump of X exists’, over RCA0 due to results of Jockusch [5]. By subjecting the theory RCA0 augmented by the latter statement to an ordinal analysis, we give a direct proof of the fact that the infinite Ramsey theorem has proof-theoretic strength εω. The upper bound is ob...
