Spectral expansion for finite temperature two-point functions and clustering

Recently, the spectral expansion of finite temperature two-point functions in integrable quantum field theories was constructed using a finite volume regularization technique and the application of multidimensional residues. In the present work, the original calculation is revisited. By clarifying some details in the residue evaluations, we find and correct some inaccuracies of the previous result. The final result for contributions involving no more than two particles in the intermediate states is presented. The result is verified by proving a symmetry property which follows from the general structure of the spectral expansion, and also by numerical comparison to the discrete finite volume spectral sum. A further consistency check is performed by showing that the expansion satisfies the cluster property up to the order of the evaluation.Comment: 38 pages, 1 eps figure

Aegyptio-Afroasiatica XXVII

During my current work on the Egyptian Etymological Word Catalogue (EEWC, ongoing since summer 1994), it has become possible to identify a great number of new lexical correspondences between Egyptian and its vast Afro-Asiatic (Semito-Hamitic) kindred. The series of papers „Aegyptio-Afroasiatica” has been started in 1995 for reporting these results. The numbering of etymological entries is continuous beginning from my very first report

Questions of Egyptian Historical Phonology and Afro-Asiatic

The new monograph on Egyptian historical grammar by J. P. Allen appeared merely some two decades after A. Loprieno’s (1995) book with similar scope and aims. In this review article,the reviewer is investigating whether the author has managed to yield a new synthesis in the swampy domain of historical phonology, by determining to what extent his material reflects and matches our knowledge on the subject hitherto accumulated on the one hand and how convincing the new solutions are on the other hand

Layers of the Oldest Egyptian Lexicon I

The paper re-examines the controversies of P. Lacau’s old observation on a binary opposition of the anatomical terminology of Ancient Egyptian in the context of many new results issuing from current progress in Afro-Asiatic (Semito-Hamitic) comparative linguistics. The presented etymological examination of the Ancient Egyptian anatomical terminology corroborated a surprising distribution: one member of the synonymous pairs is usually a Semitic word, whereas the other one(s) have non-Semitic cognate(s) solely attested in some of the African branches of our language macrofamily. A relatively deeper presence of the extra-Semitic vocabulary in Egyptian has also become apparent
