It is demonstrated that, at least within the scope of the holographic principle, an experimental value of the vacuum energy density may be derived and may be tested quite well with a new small parameter arising in a quantum theory with the fundamental length on the order of Planck’s length. Besides, within a theory proclaiming the existence of such fundamental length a high-energy deformation of the General Relativity for the space with horizon has been constructed. The obtained results have been applied to solving of the dark energy problem, making it possible to frame the following hypothesis: a dynamic cosmological term is a measure of deviation from a thermodynamic identity (the first law of thermodynamics) of the high-energy (Planck’s) deformation of Einstein equations for horizon spaces in their thermodynamic interpretation.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134217888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For description of dual phase the set of equations is received from condition that Maxwell equations conserve their electrical character under dual transformations, what corresponds to effec- tive electrical charge of dion. The mechanism of dual phase synchronization in different parts of space is revealed. It is shown, that solutions of Maxwell equations for spherical waves with zero orbital moment momentum correspond to monopole ra- diation of dion. Goldstone character of dual phase so as its geometrical character is shown. This article supplements previous investigations of G. Rainich(1) and J. Wheeler and C. Misner(2, 3). Results of this article can explain many-years failures in searching magnetic charges (monopoles).","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121862618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, we introduce Nash's equilibriu m in Hilbert space, which has two characteristics: it is a fixed point and it maximizes a utility function. Moreover, evolution and selfadjoint operators have interesting properties which allow us to study steady state in Evolutionary Game Theory. Also, we present cooperative games in co mplex systems language.The concept of cooperation is important in game theory but is somewhat subtle. The term cooperate means \"to act together, with a common purpose\". Incentive compatibility is equivalent to synergy principle, which appears naturally (to add or to multiply utilit ies, ec(34)). Finally, wein the relevant results not only proved the main theorems of Quantum Mechanics, Quantum Chemistry and its applications to salt-water but also we resolved some main questions such us: Do hydrogen-bonded networks, in which tunneling plays an important role, exist?, Ho w cooperation and entropy affect water cluster equilibria?. Can salt (ClNa) p lay an Nobel role in photo-catalysis?. The answers are: tunnel effect it is possible in salt water but not in water, because ClNa, visib le light or electricity incentive to produce catalysis or photo-catalysis.

According to this geometric under- standing of matter, the mass of a part icle depends on how much the particle-associated curved path projects onto the straight paths of the universal surrounding energy density. The reference density of free space is embodied by the most elementary actions, the photons in propagation on their least-time paths. The vacuum density with rando m distribution of photon phases displays no electromagnetic field, yet the propagation of its force carriers will level off density differences. This manifests itself as gravitation. Transformations fro m one particle to another, for examp le oscillations , are described according to Noether's theorem as changes from one action to another. This physical portrayal of quantized nature, where every entity comprises mu ltip les of the most elementary action, parallels the atomistic tenet.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128465716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They give rise to a Planck scale size lower bound of the proper length. Infinit ies arising fro m the point-like character of particles are thus avoided, expressions related to fermion propagators are finite without the need to renormalize or regularize. The quark condensate, constituent quark mass, pion mass, and pion weak decay constant are calculated within the SU(2) Nambu--Jona-Lasinio model. The nu merical values are con- sistent with known strong interaction physics if one assumes very small values of the current quark mass and effective coupling constant. The usual values of these quantities in hadron phenomenology can be interpreted as resulting fro m dressing of the very s mall bare quantities with the fluctuations. With respect to the cosmological constant it is shown that a cosmological constant term, wh ich may initially exist in the gravitational action, is \"masked\" by the fluctuations of the metric, i.e., it does not appear in the final Einstein equation. Instead, the fluctuations give rise to a cosmological constant themselves.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129544213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
