A geometric approach to generalized covering radii of linear codes
Gianira N. Alfarano, Giuseppe Marino, Alessandro Neri +1
Covering problems in coding theory are closely related to finite geometry through the interpretation of the columns of parity-check matrices as point sets in finite vector spaces.…

Segre Varieties and Desarguesian Spreads
Antonio Cossidente, Giuseppe Marino, Francesco Pavese +2
Let denote the -dimensional projective space over . We investigate the intersection of two Desarguesian -spreads of $\mathrm{PG}(kh…

A lower bound on the minimum weight of some geometric codes
Bence Csajbók, Giovanni Longobardi, Giuseppe Marino +1
The -ary code associated with the incidence structure of points and -spaces in a projective space , where , is the -subspace generated…
