A Simple Introduction to Nonstandard Analysisinfinitesimals in terms of a scale set by ordinary numbers. For a positive number to be infinitesimal, it must be greater than 0 and yet smaller than any positive number you might write using a decimal expansion. No matter how many zeros you start with in that expansion, a positive infinitesimal number will be still smaller.纠缠,缠绕 发表于 2025-3-27 14:41:56
Nonstandard Analysis in Mathematical Economicsresent some special measure-theoretic properties based on nonstandard constructions and then to illustrate how these properties can be applied to problems in game theory, general equilibrium theory and finance.共和国 发表于 2025-3-27 18:40:39
Ina Schmied-Knittel,Andreas Anton,Michael Schetscheher fuel cell components, and have matched thermal expansion coefficients (TEC) with other components. Moreover, these properties must be kept unchanged over the required lifetime of at least 40,000 h at elevated temperatures, together with hundreds of thermal cycles. Although many advances have bee土产 发表于 2025-3-27 23:33:57
