On a Reconstruction Problem of Harary and Manvel
We give a complete answer to a question raised by Harary and Manvel in 1972 [3] by proving that a finite set A of points in the plane R is uniquely determined up to translation and rotation by a multiple of 90◦ by 5 of its (|A| − 1)-element subsets given up to translation and rotation by a multiple of 90◦. This result is best-possible.
متن کاملA Ramsey problem of Harary on graphs with prescribed size
Lower bounds on the Ramsey number r(G, H), as a function of the size of the graphs G and H, are determined. In particular, if H is a graph with n lines, lower bounds for r(H) = r(H, H) and r(K,, H) are calculated in terms of n in the first case and m and n in the second case. For m = 3 an upper bound is also determined. These results partially answer a question raised by Harary about the relati...
متن کاملOn Harary Matrix, Harary Index and Harary Energy
Recently, a new molecular graph matrix, Harary matrix, was defined in honor of Professor Frank Harary, and new graph invariants (local and global) based on it were also defined and researched, Harary index is one of these invariants. The Harary matrix can be used to derive a variant of the Balaban index, Harary index was also successfully tested in several structure-property relationships, so i...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
