in this paper we consider the european continuous installment call option. then  its linear complementarity formulation is given. writing the resulted problem in variational form, we prove the existence and uniqueness of its weak solution. finally finite element method is applied to price the european continuous installment call option.

let  and  be banach algebras, ,  and . we define an -product on  which is a strongly splitting extension of  by . we show that these products form a large class of banach algebras which contains all module extensions and triangular banach algebras. then we consider spectrum, arens regularity, amenability and weak amenability of these products.

This paper introduces a G space theory and a weakened weak form (W2) using the generalized gradient smoothing technique for a unified formulation of a wide class of compatible and incompatible methods. The W2 formulation works for both finite element method settings and mesh-free settings, and W2 models can have special properties including softened behavior, upper bounds and ultra accuracy. Pa...

Nonresonant three-body decays of D and B mesons are studied. It is pointed out that if heavy meson chiral perturbation theory (HMChPT) is applied to the heavy-light strong and weak vertices and assumed to be valid over the whole kinematic region, then the predicted decay rates for nonresonant charmless 3-body B decays will be too large and especially B− → π−K+K− greatly exceeds the current expe...

The radiative decays, π ± → l ± νγ and K ± → l ± νγ, with l standing for an e or a μ, and γ for a real or virtual photon (e + e − pair), provide a powerful tool to investigate the hadronic structure of pions and kaons. The structure-dependent part SD i of the amplitude describes the emission of photons from virtual hadronic states, and is parametrized in terms of form factors F i , with i = V, ...

We calculate, in the framework of QCD sum rules and to next-to-leading order in perturbation theory, the universal function ξ3(v · v) which appears at order 1/mQ in the heavy quark expansion of meson weak decay form factors. We find that radiative corrections of order αs are very important. Over the kinematic range accessible in semileptonic decays, ξ3(v ·v′) is proportional to the leading-orde...

Functional language compilers implement only weak-head reduction. However, there are cases where head normal forms or full normal forms are needed. Here, we study how to use cps conversion for the compilation of head and strong reductions. We apply cps expressions to a special continuation so that their head or strong normal form can be obtained by the usual weak-head reduction. We remain withi...

We discuss magnetic moments of the baryons allowing for avour symmetry breaking in the quark magnetic moments. We nd that such a symmetry breaking is necessary to achieve consistency with data for the nucleon spin structure obtained from deep inelastic scattering. For the e ective magnetic moments we nd u= d = 1:79 0:06 and s= d = 0:68 0:05. We also calculate weak decay form factors, which in o...

A chiral SU(2)× SU(2) Lagrangian containing, besides the usual meson fields, their first radial excitations is considered. The Lagrangian is derived by bosonization of the Nambu– Jona-Lasinio quark model with separable non-local interactions, with form factors corresponding to 3–dimensional ground and excited state wave functions. The spontaneous breaking of chiral symmetry is governed by the N...
