On Point-cyclic Parallelisms of Pg(3, 7)
A spread of lines is a set of lines of P G(n, q), which partition the point set. A parallelism is a partition of the set of lines by spreads. A parallelism in P G(n, q) is point-cyclic if it has an automorphism group which acts as a Singer automorphism. In P G(3, 7) no point-cyclic parallelisms have been known. We claim that such do not exist. 1. Introduction. Parallelisms of projective spaces ...
متن کاملSome new classes of finite parallelisms
Some new constructions of parallelisms in PG(3, q) are given that produce parallelisms consisting of one Desarguesian spread and q + q derived Knuth semifield spreads and other types consisting of one Knuth semifield spread, one Hall spread and the remaining spreads are derived Knuth semifield spreads.
متن کاملMulticolored parallelisms of Hamiltonian cycles
A subgraph in an edge-colored graph is multicolored if all its edges receive distinct colors. In this paper, we prove that a complete graph on 2m + 1 vertices K2m+1 can be properly edge-colored with 2m+ 1 colors in such a way that the edges of K2m+1 can be partitioned intommulticolored Hamiltonian cycles. © 2009 Published by Elsevier B.V.

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
romantic education:reading william wordsworths the prelude in the light of the history of ideas
عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
