Tripled partially ordered sets

In this paper, we introduce tripled partially ordered sets and monotone functions on tripled partiallyordered sets. Some basic properties on these new dened sets are studied and some examples forclarifying are given.

Majorization for partially ordered sets

We generalize the classical notion of majorization in Rn to a majorization order for functions defined on a partially ordered set P . In this generalization we use inequalities for partial sums associated with ideals in P . Basic properties are established, including connections to classical majorization. Moreover, we investigate transfers (given by doubly stochastic matrices), complexity issue...

Combinatorial entropy and phase diagram of partially ordered ice phases.

A close analytical estimate for the combinatorial entropy of partially ordered ice phases is presented. The expression obtained is very general, as it can be used for any ice phase obeying the Bernal-Fowler rules. The only input required is a number of crystallographic parameters, and the experimentally observed proton site occupancies. For fully disordered phases such as hexagonal ice, it reco...

Entropy and phase transitions in partially ordered sets

We define the entropy function S(p) = lim.-~zn -zln N(n ,p), where N(n ,p) is the number of different partial order relations definable over a set of n distinct objects, such that of the possible n ( n I )/2 pairs of objects, a fraction p are comparable. Using rigorous upper and lower bounds for S(p), we show that there exist real numbers p1 and p2; .083 < p1 ~ 1/4 and 3/8 ~ p2 < 48/49; such th...

Cavity Formation and Light Propagation in Partially Ordered and Completely Random One-Dimensional Systems

We study light transport in ordered, partially ordered, and completely random one-dimensional (1-D) systems. In a periodic structure, there are three types of passbands with different origins. When disorder is introduced to a periodic system, the passbands change differently, depending on their origins. The transmissivity and decay length in the passbands near the band edges decrease drasticall...
