Abstract: Classical results in sparse recovery guarantee the exact reconstruction of s-sparse signals under assumptions on the dictionary that are either too strong or NP-hard to check. Moreover, such ...
Polar spaces are a fascinating area of study in geometry and combinatorics, focusing on the relationships between points, lines, and planes in various geometric configurations. Recent research has ...
Abstract: In this paper we introduce a general representtation of networks that can be modelled as planar graphs, by using oriented incidence matrices. The representation is used to obtain a unitary ...
