Lattices of flats for symplectic matroids
Or Raz
We are interested in expanding our understanding of symplectic matroids by exploring the properties of a class of symplectic matroids with a "lattice of flats". Taking a well-behav…

On the -dimensional algebraic connectivity of graphs
Alan Lew, Eran Nevo, Yuval Peled +1
The -dimensional algebraic connectivity of a graph , introduced by Jordán and Tanigawa, is a quantitative measure of the -dimensional rigidity of that i…

Sharp threshold for rigidity of random graphs
Alan Lew, Eran Nevo, Yuval Peled +1
We consider the Erdős-Rényi evolution of random graphs, where a new uniformly distributed edge is added to the graph in every step. For every fixed , we show that with high…
