Nonexistence of self-similar singularities in the ideal magnetohydrodynamics
In this paper we exclude the scenario of apparition of finite time singularity in the form of self-similar singularities in the ideal magnetohydrodynamic equations, assuming suitable integrability conditions on the vorticity and the magnetic field. We also consider more sophisticated possibility of asymptotically self-similar singularities, which means that the local classical solution converge...
متن کاملNonexistence of self-similar singularities in the viscous magnetohydrodynamics with zero resistivity
We are concerned on the possibility of finite time singularity in a partially viscous magnetohydrodynamic equations in R, n = 2, 3, namely the MHD with positive viscosity and zero resistivity. In the special case of zero magnetic field the system reduces to the NavierStokes equations in R. In this paper we exclude the scenario of finite time singularity in the form of self-similarity, under sui...
متن کاملمروری بر کتاب self-similar groups
خودسانی یا فرکتالی بودن پدیده ای مهم در طبیعت است که در بسیاری از وجوه تمدن جدید انعکاس یافته است. این پدیده علاوه بر هنر، در فیزیک، شیمی علوم پزشکی و علوم کامپیوتر نیز رخ می نماید. خودسانی در مباحث مختلفی از ریاضیات و مدلسازی ریاضی از جمله دستگاههای دینامیکی و آشوب، فرآیندهای تصادفی و فیزیک آماری، توپولوژی و هندسه فرکتالی نیز ظاهر می شود.
متن کاملSelf-similar fractals and arithmetic dynamics
The concept of self-similarity on subsets of algebraic varieties is defined by considering algebraic endomorphisms of the variety as `similarity' maps. Self-similar fractals are subsets of algebraic varieties which can be written as a finite and disjoint union of `similar' copies. Fractals provide a framework in which, one can unite some results and conjectures in Diophantine g...
متن کاملSelf-generated Self-similar Traffic
Self-similarity in the network traffic has been studied from several aspects: both at the user side and at the network side there are many sources of the long range dependence. Recently some dynamical origins are also identified: the TCP adaptive congestion avoidance algorithm itself can produce chaotic and long range dependent throughput behavior, if the loss rate is very high. In this paper w...
