Une note sur les contractions dans les polygones orthogonaux
Maire, F., Une note sur les contractions dans les polygones orthogonaux, Discrete Mathematics 111 (1993) 3677371. We define a contraction for orthogonal polygons, and show that such a polygon can be transformed into a rectangle by a sequence of contractions. This result gives a new proof of the orthogonal art gallery theorem. We present also a property of the maximal rectangles contained in ort...
متن کاملNote sur les temps de service résiduels dans les systèmes type M/G/c
RÉSUMÉ. Lorsque l’analyse exacte de certains modèles paraît difficile, on recherche des solutions approchées. C’est le cas de la file M/G/c pour laquelle les paramètres de performances moyens peuvent être calculés de façon approchée en estimant 1) le minimum des temps restants pour terminer les services des clients en cours de service et 2) la probabilité pour un client arrivant dans la file d’...
متن کاملA Note on Signs of Kloosterman Sums (une Note Sur Les Signes Des Sommes De Kloosterman)
We prove that the sign of Kloosterman sums Kl(1, 1;n) changes infinitely often as n runs through the square-free numbers with at most 15 prime factors. This improves on a previous result by Sivak-Fischler who obtained 18 instead of 15. Our improvement comes from introducing an elementary inequality which gives lower and upper bounds for the dot product of two sequences whose individual distribu...
متن کاملMémoire Sur Les Probabilités∗
I intend to treat in this Memoir two important points in the analysis of chances which do not seem yet to have been sufficiently deeply studied: the first has for object the manner of calculating the probability of events composed of simple events of which one does not know the respective probabilities; the object of the second is the influence of past events on the probability of future events...
متن کاملMémoire Sur Les Suites
The theory of series is one of the most important objects of Analysis: all problems which reduce to some approximations, and consequently nearly all the applications of Mathematics to Nature, depend on this theory; thus we see that it has principally fixed the attention of the geometers; they have found a great number of beautiful theorems and ingenious methods, either in order to expand functi...
