The Structure of Subordination5 this suggestion will be made more precise and we will see that . expresses the idea of realizability of structures. It is tempting to regard . and . themselves as relational, but I shall not pursue this line of thought here.增减字母法 发表于 2025-3-25 16:46:55
The Concept of Dependence in Applied Mathematics; a First Accounthe notion of . is another important notion I shall leave out of account. The subject matter is rather the notions of dependence and independence which are central in most applications of mathematics to science.治愈 发表于 2025-3-25 21:17:59
An Example: Social Choicelicable to both subjects. We use the terminology from social choice theory essentially in accordance with Arrow (1951, 1963), Sen (1970) and Luce & Raiffa (1957). Our purpose is primarily to exemplify what has been said in earlier sections and not to conduct an analysis of the problem of social choice.languor 发表于 2025-3-26 02:32:59

Jan Odelstadred as the aim of thermochemistry by Rossini,. many years ago. Subsequently, this purpose was broadened. to include the derivation of the heats of formation of compounds from their constituent elements and the relationship of these results to the chemical binding energies in the molecules.

Jan Odelstadhod was reasonably successful. It is limited in a major way if molecules contain strain, because the bond additivities do not in themselves include such strain. However, if the strain is independently determined, it can be added into the calculation. This was done by hand methods years ago by simply
