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...
We propose a new variational problem which we call the Split Variational Inequality Problem (SVIP). It entails finding a solution of one Variational Inequality Problem (VIP), the image of which under ...

maximal order symmetric group distribution of primes
2010/12/7
After Landau, let us define g(n) as the maximal order of a per-mutation of the symmetric group Sn on n letters. We give several estimates of the largest prime divisor P+(g(n)) of g(n).

2010/12/14
This paper develops a rst-order system least-squares (FOSLS) formulation for equations of two-phase ow. The main goal is to show that this discretization, along with numerical
techniques such as nes...
Computing the time-continuous Optimal Mass Transport Problem without Lagrangian techniques
