Geodesic structure of the cosmological Levi-Civita spacetimes

Adam Tyc, Martin Zofka

We investigate the implications of the behavior of geodesics in static, cylindrically symmetric spacetimes with a non-zero cosmological constant. We consider the symmetries of thes…

Markov chains of $Z$ -oriented triangulations of surfaces

Adam Tyc

We consider triangulations of closed $2$ -dimensional (not necessarily orientable) surfaces. Any minimal set of zigzags that double covers the set of edges provides a $z$ -orientatio…

Maximal cliques in the graph of $5$ -ary simplex codes of dimension two

Mariusz Kwiatkowski, Andrzej MatraÅ, Mark Pankov +1

We consider the induced subgraph of the corresponding Grassmann graph formed by $q$ -ary simplex codes of dimension $2$ , $q \geq 5$ . This graph contains precisely two types of maximal…
