Exponential self similar solutions technique for instability phenomenon arising in double phase flow through porous medium with capillary pressure
Immiscible fluid Instability Flows in porous media
2010/9/25
The theoretical studies involved development of the differential equations which describe the instability of water by an oil-saturated rock. The basic assumption underlying the present investigation i...
Self-similar and charged spheres in the free-streaming approximation
Characteristic Evolution Einstein{Maxwell system
2010/12/20
We evolve nonadiabatic charged spherical distributions of matter. Dis-sipation is described by the free{streaming approximation. We match a self{similar interior solution with the Reissner{Nordstrom{...
Nontangential limits and Fatou-type theorems on post-critically finite self-similar sets
Fatou-type theorems post-critically finite self-similar sets
2010/11/18
In this paper we study the boundary limit properties of harmonic functions on $\mathbb R_+\times K$, the solutions $u(t,x)$ to the Poisson equation \[ \frac{\partial^2 u}{\partial t^2} + \Delta u = 0...
From Self-Similar Structures to Self-Similar Groups
From Self-Similar Structures Self-Similar Groups
2010/11/15
We explore the relationship between limit spaces of contracting self-similar groups and fractals. Exact conditions on a group are given under which its limit space has a self-similar structure and a ...

Heat conduction telegraph-type model self-similar behavior of solutions II
2010/12/15
In our former study (J. Phys. A: Math. Theor. 43, (2010) 325210 or arXiv:1002.0999v1 [math-
ph]) we introduced a modified Fourier-Cattaneo law and derived a non-autonomous telegraph-type
heat conduc...
Estimates for the resolvent kernel of the Laplacian on p.c.f. self similar fractals and blowups
resolvent kernel Laplacian on p.c.f. self similar fractals blowups
2010/12/14
One of the main features of analysis on post-critically finite self-similar (pcfss) sets is
that it is possible to understand the behavior of the Laplacian and its inverse, the Green
operator, in te...
Truncation errors in self-similar continuous unitary transformations
Truncation errors self-similar continuous unitary transformations
2010/10/27
Effects of truncation in self-similar continuous unitary transformations (S-CUT) are estimated
rigorously. We find a formal description via an inhomogeneous flow equation. In this way, we are able to...

2010/12/15
For a large class of self-similar random sets F in Rd geometric parameters Ck(F), k = 0, . . . , d, are introduced. They arise as a.s. (average or essential) limits of the volume Cd(F(")), the surface...
For a large class of self-similar sets F in Rd, analogues of the higher order mean curvatures
of differentiable submanifolds are introduced, in particular, the fractal Gauss-type curvature.
They are...

Degenerate self-similar measures spectral asymptotics small deviations of Gaussian processes
2010/12/1
The problem of small ball behavior for the norms of Gaussian processes is intensively studied
in recent years. The simplest and most explored case is that of L2-norm. Let us consider a
Gaussian proc...

Self-similar pattern formation and continuous mechanics of self-similar systems
crack growth formation starts isotropically oriented crack
2009/5/7
In many cases, the critical state of systems that reached the threshold is characterised by self-similar pattern formation. We produce an example of pattern formation of this kind – formation of self-...
