O(N) models within the local potential approximation
Using Wegner-Houghton equation, within the Local Potential Approximation, we study critical properties of O(N) vector models. Fixed Points, together with their critical exponents and eigenoperators, are obtained for a large set of values of N , including N = 0 and N → ∞. Polchinski equation is also treated. The peculiarities of the large N limit, where a line of Fixed Points at d = 2+2/n is pre...
متن کاملThe Local Potential Approximation for the Brueckner G-matrix
The Brueckner G-matrix for a slab of nuclear matter is analyzed in the singlet 1 S and triplet 3 S + 3 D channels. The complete Hilbert space is split into two domains, the model subspace S 0 , in which the two-particle propagator is calculated explicitly, and the complementary one, S ′ , in which the local potential approximation is used. This kind of local approximation was previously found t...

متن کاملThe approximate solutions of Fredholm integral equations on Cantor sets within local fractional operators
In this paper, we apply the local fractional Adomian decomposition and variational iteration methods to obtain the analytic approximate solutions of Fredholm integral equations of the second kind within local fractional derivative operators. The iteration procedure is based on local fractional derivative. The obtained results reveal that the proposed methods are very efficient and simple tools ...
متن کاملAnalysis of the Effect of Regional Creativity on Regional Economic Growth within New Economic Geographical Models
A mong the theories explaining the relationship between creativity criteria in cities and economic growth, “Human Capital Theory” by Glaeser and “Creative Class theory” by Florida can be mentioned. Accordingly, present paper aimed at analysis of the creativity effect on regional economic growth and is presented in two theoretical and experimental parts. Considering the results of the curre...
