Notes on fk analysis of surface waves
Rayleigh waves soil stiffness shear wave profiles shallow geophysics shear modulus
2015/9/29
The dispersive nature of Rayleigh waves is the basis of many identification procedures to infer the site stiffness profile from surface measurements. This article presents some important aspects relat...
NOTES ON A PAPER OF MESS
NOTES PAPER OF MESS
2015/9/29
In his 1990 paper “Lorentz Spacetimes of Constant Curvature” [82], Geoff Mess
offered what was, at the time, a completely new approach to the study of spacetimes in 2 + 1-dimensions, prim...
Nothing found here is original except for a few mistakes and misprints here and there. These notes are simply a record of what I cover in class, to spare the students the necessity of taking the lectu...

Waves in weakly random media:lecture notes for the Vienna Inverse Problems school
weakly random media Vienna Inverse Problems
2015/7/14
Wave propagation in complex media is an ubiquitous phenomenon–applications include light propagation through the atmosphere, underwater acoustic, tomography, and innumerable other ones. These problems...
The Technion school lecture notes:the moving plane method,or doing PDEs in a cafe
Technion school lecture notes moving plane method doing PDEs a cafe
2015/7/14
We will have two main characters in these notes: the maximum principle and the sliding method. The latter has a twin, the moving plane method–they are often so indistinguishable that we will count the...

Lecture Notes in Computer Science: Incompleteness, uncertainty and autonomy: Intelligent systems
Incompleteness uncertainty autonomy
2014/8/8
We are producing an innovative theory to make a group of autonomous
systems as intelligent as possible to serve as surrogate human decision makers in a
hybrid group of humans and machines for a va...
Notes on the peripheral volume of hyperbolic 3-manifolds
Notes the peripheral volume hyperbolic 3-manifolds Geometric Topology
2012/6/27
We consider hyperbolic 3-manifolds with either non-empty compact geodesic boundary, or some toric cusps, or both. For any such M we analyze what portion of the volume of M can be recovered by insertin...
Notes on the Schwinger model: regularization and gauge invariance
the Schwinger model regularization and gauge invariance Mathematical Physics
2012/6/21
The point-splitting computation of the gauge invariant Hamiltonian for the Schwinger model on the circle in a positive energy representation is presented.
A space is od-compact (resp. od-Lindel\"of) provided any cover by open dense sets has a finite (resp. countable) subcover. We first show with simple examples that these properties behave quite poorly ...
