1. 1. Local Rigidity of Some Lie Group Actions

   University essay from KTH/Matematik (Avd.)

   Abstract : In this paper we study local rigidity of actions of simply connected Lie groups. In particular, we apply the Nash-Moser inverse function theorem to give sufficient conditions for the action of a simply connected Lie group to be locally rigid. Let $G$ be a Lie group, $H < G$ a simply connected subgroup and $\Gamma < G$ a cocompact lattice. READ MORE

3. 2. Focal Operations with Network Distance Based Neighbourhoods : Implementation, Application and Visualization

   University essay from KTH/Geoinformatik

   Author : Nore Ottenby; [2015]
   Keywords : GIS; Map algebra; Focal sum; Focal Proximity; Network Analysis; Network Space; Location Problem; City Planning; Arcpy; Density map; Hotspot map;

   Abstract : In spatial analysis, many operations are performed considering the neighbouring locations of a feature. The standard definition of a neighbourhood is an area confined by geometrical length and direction with respect to its focus. When allocating a location for a service, the population distribution is often considered. READ MORE
