Varieties with log terminal and log canonical singularities are considered in the Minimal Model Program, see [KMM] for introduction. In [SH2] it was conjectured that many of the interesting sets, associated with these varieties have something in common: they satisfy the ascending chain condition, which means that every increasing chain of elements terminates (in [SH2] it was called the upper se...

We establish the dichotomy property of [7] for multi-conclusion stable canonical rules of [1]. This yields an alternative proof of existence of bases of admissible rules for such well-known systems as IPC, S4, and K4.

In [I] we introduced the notion of transfer from a group over a local field to an associated endoscopic group, but did not prove its existence, nor do we do so in the present paper. Nonetheless we carry out what is probably an unavoidable step in any proof of existence: reduction to a local statement at the identity in the centralizer of a semisimple element, a favorite procedure of Harish Chan...

In this note, we prove the existence of Nash equilibria in infinite normal form games with compact sets of strategies and continuous payoffs by constructing Nash mappings. © 2010 Elsevier Ltd. All rights reserved.

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...

the cause is the basis of the existence and non-existence of a thing and its consideration is prior to consideration of the thing. in accordance with subjective theory, the will is the substance of the contract and the other elements of a contract are conditions of will’s efficiency. in contrast, according to objective theory, object of the contract is the substance of it and the other elements...

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.
