Electrified thin films:Global existence of non-negative solutions
Higher order equation Non-local equation Thin film equation Non-negative solutions
2015/10/15
We consider an equation modeling the evolution of a viscous liquid thin film wetting a horizontal solid substrate destabilized by an electric field normal to the substrate. The effects of the electric...

With the development of computers, network communications, scientific computing, mapping remote sensing and geographic
information technologies, Discrete Global Grids (DGGs) and Earth System Spatial...
Let X be a manifold. The classification of all equivariant bilinear maps between tensor density modules over X has been investigated by Yu Grozman, who has provided a full classification for those whi...
On a Conjecture on the weak global dimension of Gaussian rings
Gaussian rings weak dimension content non-noetherian rings
2011/8/24
Abstract: Bazzoni and Glaz conjecture that the weak global dimension of a Gaussian ring is 0,1 or \infty. In this paper, we prove their conjecture in all cases except when R is a non-reduced local Gau...
We investigate the collective dynamics of bursting neurons on clustered network. The clustered
network is composed of subnetworks each presenting a small-world property, and in a given sub-
network ...
