-Veronese variety and some applications
Nicola Durante, Giovanni Longobardi, Valentina Pepe
Let be the Galois field of order a prime, be the automorphism group of and $\boldsymbolσ=(…
A construction for clique-free pseudorandom graphs
Anurag Bishnoi, Ferdinand Ihringer, Valentina Pepe
A construction of Alon and Krivelevich gives highly pseudorandom -free graphs on vertices with edge density equal to . In this short note we improve thei…
On varieties defined by large sets of quadrics and their application to error-correcting codes
Simeon Ball, Valentina Pepe
Let be a -dimensional subspace of quadratic forms defined on with the property that does not contain any reducible quad…
Non-intersecting Ryser hypergraphs
Anurag Bishnoi, Valentina Pepe
A famous conjecture of Ryser states that every -partite hypergraph has vertex cover number at most times the matching number. In recent years, hypergraphs meeting this c…
A non-existence result on symplectic semifield spreads
Stefano Capparelli, Valentina Pepe
We prove that there do not exist non-Desarguesian symplectic semifield spreads of PG, even, whose associated semifield has center containing ,…
Forbidden subgraphs in the norm graph
Simeon Ball, Valentina Pepe
We show that the norm graph constructed in [J. Kollár, L. Rónyai and T. Szabó, Norm-graphs and bipartite Turán numbers, Combinatorica, 16 (1996) 399--406] with vertices about $…
On codewords in the dual code of classical generalised quadrangles and classical polar spaces
Valentina Pepe, Leo Storme, Geertrui Van de Voorde
In [9], the codewords of small weight in the dual code of the code of points and lines of Q(4, q) are characterised. Inspired by this result, using geometrical arguments, we charac…
Families of twisted tensor product codes
Luca Giuzzi, Valentina Pepe
Using geometric properties of the variety $\cV_{r,t}$, the image under the Grassmannian map of a Desarguesian -spread of $\PG(rt-1,q)$, we introduce error correcting codes r…
