The chords' problem is a variant of an old problem of computational geometry: given a set of points of n , one can easily build the multiset of the distances between the poi...
Polygon spaces like Mℓ = {(u1, · · · , un) ∈ S1 × · · · S1 ; n i=1 liui = 0}/SO(2) or they three dimensional analogues Nℓ play an important rle in geometry and topolo...
In this paper we describe a procedure to reduce the size of the input feature vector. A complex pattern recognition problem like face recognition involves huge dimension of input ...

Critical kernels constitute a general framework settled in the of abstract complexes for the study of parallel thinning in any dimension. We take advantage of the properties of thi...
High complexity of lattice construction algorithms and uneasy way of visualising lattices are two important problems connected with the formal concept analysis. Algorithm complexi...
