the subject of the present article is the problem concerning the unity of attributes and its relation to the unity of referent and multiplicity of concepts. in this problem, the theory of non-revealingness (‘adam-i kāshifiyat) of the multiplicity of concepts from multiplicity of referent is proved; and the rival theory, i.e., the revealingness of the multiplicity of concept from the multiplicit...

We prove existence of a competitive equilibrium in a version of a Ramsey model in which leisure enters the utility function. The analysis is carried out by means of a direct and technically simple approach that allows us to obtain detailed results concerning the behavior of equilibrium allocations and prices.

A deterministic compartmental model for the transmission dynamics of onchocerciasis with nonlinear incidence functions in two interacting populations is studied. The qualitatively analyzed to investigate its local asymptotic behavior respect disease-free and endemic equilibria. It shown, using Routh-Hurwitz criteria, that equilibrium locally asymptotically stable when associated basic reproduct...

the present paper aims at clarifying the role of the concept “walåyah” in the philosophy of the unity of being in islamic philosophy (waedat al-wujid). the concept “walåyah” is deeply built into the philosophic system of the islamic theory of being, and moreover the dynamic aspect of this concept has always activated islamic philosophy of existence and stimulated the thought of islamic philosop...

Wolfmann [Wolfmann, 1992] introduced the idea of ZCZ binary sequences with the so-called almost perfect sequences, which have one non-zero off-peak autocorrelation value. Non-binary ZCZ sequences over roots of unity were first constructed by Suehiro [Suehiro, 1994]. Other types of ZCZ sequences have been constructed based on the existence of complementary pairs [Suehiro, 1994][Fan, 1999a][Matsu...

We prove that the triviality of the Galois action on the suitably twisted odd-dimensional étale cohomogy group with finite coefficients of an absolutely irreducible smooth projective variety implies the existence of certain primitive roots of unity in the field of definition of the variety. This text was inspired by an exercise in Serre’s Lectures on the Mordell–Weil theorem.
