Notes: Abstract In two recent papers Ruelle gave a heuristic theory of phase transitions, using some techniques introduced by Israel. He proves a version of Gibbs phase rule, assuming a differentiability condition for the pressure. Ruelle already pointed out that his condition cannot always hold. In this paper we prove that the interaction spaces which he considers are in general too large for his condition to hold. We also show that the version of the Gibbs phase rule which is a consequence of this condition does not hold in general. Moreover we give some constraints on the analyticity properties of the pressure.

Notes: Summary The mitochondrial DNA (mtDNA) of Japanese patients suffering from the syndrome of mitochondrial myopathy, encephalopathy, lactic acidosis and strokelike episodes (MELAS) exhibits a specific heteroplasmic A→G transition in the tRNALeu at position 3243. In this study, we investigated mtDNA from skeletal muscle, cardiac muscle, brain, liver, diaphragm, fibroblasts and blood cells of four Caucasians with MELAS, one younger healthy sister of two MELAS patients, and eleven controls. We found that 1) the mutation was present in all investigated tissues of Caucasians with MELAS but not in controls, 2) within a single patient, the tissue-specific variation of the copy number of mutated mtDNA covered the same range as in the skeletal muscle of different patients, 3) the mutation was also present in the blood cells of the healthy sister of two MELAS siblings.

Notes: Abstract One-dimensional Ising spin systems interacting via a two-body random potential are considered; a decay with the distance like 1/r 1+ε is assumed. We consider only boundary conditions independent of the random realization of the interactions and prove uniqueness and cluster properties of Gibbs states with probability one.

Notes: Abstract We prove the absence of continuous symmetry breaking at arbitrary temperatures for two-dimensionalN-vector spin glass models with Hamilton function $$H = - \sum\limits_{i,j} {J(i,j)\left| {i - j} \right|^{ - 2 - \varepsilon } S_i \cdot S_j ,} \varepsilon 〉 0$$ whereJ (i, j) has mean 0 and variance 1, for alli, j. We comment on the role of boundary conditions in spin glasses and on their critical behaviour in high dimensions.

Notes: Abstract We construct a class of non-symmetry breaking pair interactions, which change the phase diagram of then.n. Ising and classicalX Y model. Furthermore we improve earlier obtained constraints on the decrease of interactions, necessary to get analyticity properties of the pressure in manifolds of non-symmetry breaking interactions.

Notes: Abstract Various possible precise definitions of an Edwards-Anderson type of order parameter for an Ising model spin glass are considered, using boundary conditions for a finite system, states of an infinite system, and a duplicate-system approach. Several of these definitions are shown to yield identical results.

Notes: Abstract: We investigate the complete analyticity (CA) of the two-dimensional q-state Potts model for large values of q. We are able to prove it for every temperature , provided we restrict ourselves to nice subsets, their niceness depending on the temperature T. Contrary to this restricted complete analyticity (RCA), the full CA is known to fail for some values of the temperature above . Our proof is based on Pirogov-Sinai theory and cluster expansions for the Fortuin-Kasteleyn representation, which are available for the Potts model at all temperatures, provided q is large enough.
