Inner Fluctuations of the Spectral Action
نویسندگان
چکیده
where f is a positive even function of the real variable and the parameter Λ fixes the mass scale. The dimension of a noncommutative geometry is not a number but a spectrum, the dimension spectrum (cf. [6]) which is the subset Π of the complex plane C at which the spectral functions have singularities. Under the hypothesis that the dimension spectrum is simple i.e. that the spectral functions have at

Least Squares Techniques for Extracting Water Level Fluctuations in the Persian Gulf and Oman Sea
Extracting the main cyclic fluctuations from sea level changes of the Persian Gulf and Oman Sea is vital for understanding the behavior of tides and isolating non-tidal impacts such as those related to climate and changes in the ocean-sea circulations. This study compares two spectral analysis methods including: Least Squares Spectral Analysis (LSSA) and Least Squares Harmonic Estimation (LSHE)...
متن کاملAnalysis of the Characteristics, Physical Concepts and Entropy Generation in a Turbulent Channel Flow Using Vortex Blob Method
In this paper, using vortex blob method (VBM), turbulent flow in a channel is studied and physical concepts of turbulence are obtained and discussed. At first, time-averaged velocities, and , and then their fluctuations are calculated. To clarify turbulence structures, velocity fluctuations and are plotted. It is observed that turbulence structures occupy different positions and move with con...
متن کاملNumerical study of heat gradient and crossing energy to around building walls containing phase change materials in Kashan temperature conditions
The application of phase change materials (PCM) in the variant parts of building because of the high capacity these materials, lead to an improvement in temperature conditions and reduction in energy consumption. Due to the high dependency of the performance of these materials to the ambient temperature fluctuations, their applications in climates with extreme temperature fluctuations has a sig...
متن کاملOn two classes of third order boundary value problems with finite spectrum
The spectral analysis of two classes of third order boundary value problems is investigated. For every positive integer $m$ we construct two classes of regular third order boundary value problems with at most $2m+1$ eigenvalues, counting multiplicity. These kinds of finite spectrum results are previously known only for even order boundary value problems.
متن کاملInterpretation of the Structure Function of Rotation Measure in the Interstellar Medium
The observed structure function (SF) of rotation measure (RM) varies as a broken power-law function of angular scales. The systematic shallowness of its spectral slope is inconsistent with the standard Kolmogorov scaling. This motivates us to examine the statistical analysis on RM fluctuations. The correlations of RM constructed by Lazarian & Pogosyan are demonstrated to be adequate in explaini...
