Academy of Mathematics and Systems Science, CAS Colloquia & Seminars： On the dimension of limit sets on the real projective plane via stationary measures
实射影平面 极限集 维数 平稳测度
2023/11/29
I will present a dimension jump result of limit sets on RP^2 for representations of surface groups in SL(3,R). For Anosov representations, we prove the equality between the Hausdorff dimension and the...

Astronomers have obtained observations of the smallest asteroid ever characterized in detail. At 2 meters (6 feet) in diameter, the tiny space rock is small enough to be straddled by a person in a hyp...
ESTIMATION OF AERODYNAMIC ROUGHNESS AND ZERO PLANE DISPLACEMENT USING MEDIUM DENSITY OF AIRBORNE LIDAR DATA
Airborne LiDAR Aerodynamic Roughness Length Zero Plane Displacement Forest
2016/10/14
This paper presents a framework to estimate aerodynamic roughness over specific height (zo/H) and zero plane displacement (d/H) over various landscapes in Kelantan State using airborne LiDAR data. The...

2016年4月5日下午，国际著名空间和大气化学专家、英国利兹大学化学研究与创新中心主任、Priestley国际气候中心副主任、2005年英国皇家化学会化学反应机制动力学奖获得者John Plane教授在水上报告厅为我校师生作了题为“宇宙尘埃、彗星、流星和气候”(Cosmic Dust, Comets, Meteors and Climate)的学术报告。本次报告为“地球和空间科学杰出讲座”系列报告...
We investigate a one-dimensional model describing the motion of liquid drops sliding down an inclined plane (the so-called quasi-static approximation model). We prove existenceand uniqueness of a solu...

Fault plane solutions of crustal earthquakes in Southern Italy (1988-1995): seismotectonic implications
southern Italy focal mechanisms seismicity stress distribution
2015/9/28
The Southern Apennines and the Sicilian-Calabrian regions belong to the complex geodynamic Central Mediterranean area, which is dominated by the NNW-SSE convergence of the European and African plates ...
Finiteness of central configurations of five bodies in the plane
Finiteness central configurations five bodies in the plane
2015/9/25
We prove there are finitely many isometry classes of planar central configurations (also called relative equilibria) in the Newtonian 5-body problem, except perhaps if the 5-tuple of positive masses b...
Earthquake fault-plane solutions and patterns of seismicity within the Umbria Region,Italy
fault-plane solution seismicity seismotectonic Italy
2015/9/8
In this paper we present a review of the seismotectonic features (an analysis of earthquake focal mechanisms and the distribution of seismicity) of the Northern Apennines, Umbria Region (Italy) in the...
Faulting mechanism of the Campania–Lucania 1980 earthquake, Italy, from high-resolution, 3D velocity structure, aftershock relocation, fault-plane solutions, and post-seismic deformation modeling
Campania-Lucania 1980 earthquake analyses of the post-seismic data
2015/8/27
This study performs a detailed reconstruction of the rupture mechanism of the 1980 Campania–Lucania (southern Italy) earthquake. This is achieved by relocation of the main event through computation of...
A PROOF OF THE UNIFORMIZATION THEOREM FOR ARBITRARY PLANE DOMAINS
UNIFORMIZATION THEOREM ARBITRARY PLANE DOMAINS
2015/8/26
We present a simple constructive proof of the Uniformization Theorem which works for plane domains. The proof is a combination of covering space theory and Koebe's constructive proof of the Riemann ma...
Fault-plane solutions from moment-tensor inversion and preliminary Coulomb stress analysis for the Emilia Plain
Emilia 2012 earthquakes Moment tensors Focal mechanisms Coulomb static stress
2015/8/26
We investigate the seismicity occurred in the Po area, in the period July 2011-June 1012, by means of moment tensor and we use our set of revised focal mechanisms - computed for M> 3.7 earthquakes - t...
RECURSIONS FOR CHARACTERISTIC NUMBERS OF GENUS ONE PLANE CURVES
CHARACTERISTIC PLANE CURVES
2015/7/14
Characteristic numbers of families of maps of nodal curves to P2 are de ned as
intersection of natural divisor classes. (This de nition agrees with the usual de nition for
families of plane curves.)...

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...
