INSTABILITIES ON ALPINE TEMPERATE GLACIERS: NEW INSIGHTS ARISING FROM THE NUMERICAL MODELLING OF ALLALINGLETSCHER (VALAIS, SWITZERLAND)

Instabilities on Alpine temperate glaciers: new insights arising from the numerical modelling of Allalingletscher (Valais, Switzerland)

The processes leading to a glacier instability depend on the thermal properties of the contact between the glacier and its bedrock.Assessing the stability of temperate glacier (i.e.the glacier can slide on its bedrock) remains problematic.In order to scrutinize in more detail the processes governing such "sliding" instabilities, a numerical model d

Structure of intersection graphs

Let G be a finite group and let N be a fixed normal subgroup of G.In this paper, a new kind of graph on G, namely the intersection graph is defined and studied.We use 817513010002 to denote this graph, with its vertices are all normal subgroups of G and two distinct vertices are adjacent if their intersection in N.We show some properties of this gr
