Opis:: Eastern Cycle Trail Green Velo has a tremendous potential to become a recognizable brand tourism product for Polish and foreign tourists which will present a strong competition against a wide variety of cycling trails already existing in Poland and Europe. In order to achieve this goal, however, one has to implement an effective management model of Green Velo Trail in the years 2016-2020. A recommended management system for Green Velo trail is the tourism cluster. By implementing a proper management model one will avoid the risk of potential coherence loss, both in marketing and operational aspects of the trail. Moreover, it will allow to introduce competitive tourism offers and sales packages to the market and ensure the so called “project durability”. In developing Green Velo product one should benefit from the experience of the existing clusters which have already achieved a significant marketing and PR success, such as Tourism Tropical North Queenisland. Fully functional tourism product based on the idea of a cluster will fully enhance tourism economy of Eastern Poland.

Opis:: For a graph H, define $\overline{\sigma}_2(H)=min\{d(u)+d(v)|uv∈E(H)\}$. Let $H$ be a 2-connected claw-free simple graph of order $n$ with $\delta(H) ≥ 3$. In [J. Graph Theory 86 (2017) 193–212], Chen proved that if $\overline{\sigma}_2(H)≥\frac{n}{2}−1$ and $n$ is sufficiently large, then $H$ is Hamiltonian with two families of exceptions. In this paper, we refine the result. We focus on the condition $\overline{\sigma}_2(H)≥\frac{2n}{5}−1$, and characterize non-Hamiltonian 2-connected claw-free graphs $H$ of order $n$ sufficiently large with $\overline{\sigma}_2(H)≥\frac{2n}{5}−1$. As byproducts, we prove that there are exactly six graphs in the family of 2-edge-connected triangle-free graphs of order at most seven that have no spanning closed trail and give an improvement of a result of Veldman in [Discrete Math. 124 (1994) 229–239].
