The Several Dimensional Gambler's Ruin Problem
, 2016 We consider the simple random walk on the $N$-dimensional integer lattice from the perspective of evaluating asymptotically the duration of play in the multidimensional gambler\apost s ruin problem. We show that, under suitable rescalings, all $p$-moments of exit-times from balls in the $L$-infinity metric, and all $p$-moments of partial-maxima values ...

An estimate for the ruin probability in a model with variable premiums and with investments in a bond and several stocks [PDF]
Theory of Probability and Mathematical Statistics, 2008 We consider a risk process generalizing the classical Cramer-Lundberg process. The feature of the process is that its price function depends on the current reserve of an insurance company as well as on its portfolio consisting of a riskless bond and a finite number of risky assets, modeled by geometric Brownian motions.

Advanced Functional Materials, EarlyView.A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...

Chemically Fueled Systems Chemistry Across Length Scales
Advanced Functional Materials, EarlyView.Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Ruin theory in collective risk models [PDF]
, 2021 RESUMEN: Analizamos el concepto de riesgo para describir la vulnerabilidad de una compañía de seguros a la insolvencia o ruina. Se presentan algunos modelos de riesgo, a tiempo discreto y a tiempo continuo (modelo clásico de Cramer-Lundberg), junto con ...

Some stable algorithms in ruin theory and their application [PDF]
, 1995 In this paper we present a stable recursive algorithm for the calculation of the probability of ultimate ruin in the classical risk model. We also present stable recursive algorithms for the calculation of the joint and marginal distributions of the ...

Calculating multivariate ruin probabilities via Gaver–Stehfest inversion technique. [PDF]
Multivariate characteristics of risk processes are of high interest to academic actuaries. In such models, the probability of ruin is obtained not only by considering initial reserves u but also the severity of ruin y and the surplus before ruin x.

Distribution function of surplus prior to ruin [PDF]
, 2002 In a study by David Dickson, entitled On the Distribution of Surplus Prior Ruin, presented a method in finding the distribution of surplus prior to ruin with the use of probability of severity of ruin.
