The Boltzmann Distribution through a Maximum Entropy Principle
The maximum-entroy distribution is derived for the Wienr-Shannon entropy for absolutely continuous distributions when the mean value of a function in a suitable class is prescribed. Three cases are studied, according as to whether the distribution has support in a closed interval, on the non-negative half line or on the real line
Orlicz Metrics Derive from a Single Probabilistic Metric
It is shown that the same probabilistic metric as used by Schweizer and Sklar to obtain all space metrics can be used to drive the metrics of Orlicz spaces
Sopra alcune proprietĂ dell'entropia dipendente dall'errore
Si studiano alcune proprietĂ dell'entrpia dipendente dall'errore; allo scopo si introducono alcune operazioni sullo spazio delle funzioni di ripartizione
Product Topologies on the Space of Distribution Functions
We study the connection between weak convergence in the space of multiple distribution functions and convergence in the product topology induced on the product by the metrics on these spaces. We show that, for r>1 , weak convergence in is slightly more general than convergence in either product topology on . We also give several sufficient conditions under which these two modes of convergence are equivalent
A New Metric for Weak Convergence
We introduce a new metric for weak convergence in the space of positive finite measures on the Borel sets of a separable metric space . This metric derives from a norm on the space of finite rela measures on . Convergence with respect to this norm is not equivalent to weak convergence for measures on rather than
Information Theoretic Interpretation of Forte's Entropy for the Grand Canonical Ensemble
Forte's characterization of the entropy of a grand canonical ensemble in statistical mechanics has a natural interpretation in information theory. This entropy is also shown to be finite under the naturalassumption that the average message length be finite. In the proof, an analogue of the well-known inequality of Shannon is obtained
Two Uniqueness Problems Connected with Lewis' Principle
The application of Lewis's principle depends on the existence and the uniqueness of the solutions of a certain class of variational problems. We show that in two cases of particular physical interest uniquenes can beestablished in a rigorous manner
