چکیده

In this paper we prove that the centered three-dimensional Wiener sausage can be strongly approximated by a one-dimensional Brownian motion running at a suitable time clock. The strong approximation gives all possible laws of iterated logarithm as well as the convergence in law in terms of process for the normalized Wiener sausage. The proof relies on Le Gall [10]’s fine L-norm estimates between the Wiener sausage and the Brownian intersection local times.

Moderate deviations and laws of the iterated logarithm for the volume of the intersections of Wiener sausages

Using the high moment method and the Feynman-Kac semigroup technique, we obtain moderate deviations and laws of the iterated logarithm for the volume of the intersections of two and three dimensional Wiener sausages.

On the Expected Surface Area of the Wiener Sausage

There exists an extensive literature on Wiener sausages; see e.g. [25] and the references therein. Nevertheless, relatively little is known so far about the geometry of Wiener sausages due to the complex nature of their realizations. One possible description of the geometric structure of (sufficiently regular) subsets of R is given by their d + 1 intrinsic volumes or Minkowski functionals inclu...

Replica overlap and covering time for the Wiener sausages among Poissonian obstacles

We study two objects concerning the Wiener sausage among Poissonian obstacles. The first is the asymptotics for the replica overlap, which is the intersection of two independent Wiener sausages. We show that it is asymptotically equal to their union. This result confirms that the localizing effect of the media is so strong as to completely determine the motional range of particles. The second i...

On the volume of the intersection of two Wiener sausages

For $a>0$, let $W_i^a(t)$ be the $a$-neighbourhoods of the $i$th copy of a standard Brownian motion in $\Bbb R^d$ starting at 0, until time $t$. The authors prove large deviations results about $|V_2^a(ct)|=|W_1^a(ct)\cap W_2^a(ct)|$, for $d\geq2$, and suggest extensions applicable to $|V_k^a(ct)|$, the volume of the intersection of $k$ sausages. In particular, for $d\geq3$, $${\log{\rm Pr}[|V_...

اکستروژن سه بعدی به روش میدان خطوط لغزش

Many metal forming problems have been solved using the slip line field method but all of them have either been two-dimensional (plane strain or plain stress) or axisymmetric problems. In this paper a procedure has been proposed by which the slip line field solution to three dimensional problems of metal forming becomes possible. For this purpose the extrusion of shaped sections has been taken a...
