moments of the present value of total dividends and related problems in the risk model with delayed claims
in this paper, a compound binomial risk model in the presence of a constant dividend barrier is studied. two types of individual claims, main claims and by-claims, are defined, where every by-claim is induced by the main claim randomly and may be delayed for one time period with a certain probability. in the evaluation of the moments of the present value of dividends, the interest rates are ass...

Winter 2004 A ll truths are easy to understand once they are discovered,” wrote astronomer Galileo Galilei. “The point is to discover them.” The 17th-century Italian is best known as the inventor of the telescope, but if he’d been drawn to the life sciences instead of the physical sciences, he might have conceived of the microscope. As it was, the idea of using lenses to see tiny rather than fa...
متن کاملFrequency Moments
DEFINITION Consider a stream (i.e., an ordered list) S = a1, a2, . . . , an of elements ai ∈ [m] def = {1, 2, . . . ,m}. For i ∈ [m], its frequency fi is the number of times it occurs in S. The k-th frequency moment Fk of S, for real k > 0, is defined to be Fk(S) = ∑ i∈[m] f k i . Interpreting 0 0 as 0, we also define F0 this way, so that it equals the number of distinct elements in S. Observe ...
متن کاملNuclear Moments
Spins, electromagnetic moments and radii are basic observables characterizing a particular nucleus. We review a variety of experimental techniques currently used to measure these quantities for unstable nuclei far from stability and for isomeric nuclear states. The experiments can be traced back to two different principles: Optical high-resolution spectroscopy reveals the interaction between nu...
