چکیده
Abstract The objective of this work is the study probability occurrence phase portraits in a family planar quasi-homogeneous vector fields quasi degree q , that natural extension linear fields, which correspond to $$q=1.$$ q = 1 . We obtain exact values corresponding probabilities terms simple one-variable definite integral only depends on . This explicitly computable case, recovering known results, and it can be expressed either complete elliptic integrals or generalized hypergeometric functions non-linear one. Moreover, appears remarkable phenomenon when even: have center positive, contrast with what happens also odd, where zero.

construction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

In studies of radiation from partially coherent sources the so-called quasi-homogeneous (QH) model sources have been very useful, for instance in elucidating the behavior of fields produced by thermal sources. The analysis of the fields generated by such sources has, however, been largely carried out in the framework of scalar wave theory. In this paper we generalize the concept of the QH sourc...
متن کاملChern Classes of Logarithmic Vector Fields for Locally Quasi-homogeneous Free Divisors
Let X be a nonsingular complex projective variety and D a locally quasihomogeneous free divisor in X. In this paper we study a numerical relation between the Chern class of the sheaf of logarithmic derivations on X with respect to D, and the Chern-Schwartz-MacPherson class of the complement of D in X. Our result confirms a conjectural formula for these classes, at least after push-forward to pr...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
