Infinite Series of Generalized Gosper Space Filling Curves,the computer search and some geometrical insight, we conjecture that the degree . satisfies .?=?6.?+?1. We investigate the existence of infinite series of generalized Gosper curves. We show how to generate these series and introduce two new methods, the ‘decomposition method’ and the ‘modified layer method’.

Hamiltonicity of Complements of Total Graphs,djacent or incident in .. In this paper, we show that the complement of total graph .(.) of a simple graph . is hamiltonian if and only if . is not isomorphic to any graph in {. .| .?≥?1}?∪?{. .?+?. .| .?≥?1}?∪?{. .?+?.| .?≥?2}?∪?{. .?+?2. ., . .?+?,. ., . .?+?2. ., . .}.

Contractible Edges in a ,-Connected Graph,An edge of a .-connected graph is said to be .-contractible if the contraction of the edge results in a .-connected graph. Some results concerning .-contractible edges in a .-connected graph are presented.
