Obserwacje za życia nad tworzeniem się pirenoidów u skrętnicy [Observations vitales sur la formation des pyrenoïdes chez Spirogyra]

Sur la Probabilité des résultats moyens des Observations∗

The question that I myself propose to treat in this Memoir has already been the object of the works of many geometers, and particularly of Mr. Laplace, of whom the researches on this interesting matter are reunited in the Théorie analytique des Probabilités (Book II, Chapter IV), and in the three supplements to this great work. The generality of the analysis of Mr. Laplace, the variety and the ...

L’inclinaison Moyenne Des Orbites Des Comètes Sur La Figure De La Terre Et Sur Les Fonctions

One of the most extraordinary phenomena which the system of the world offers to us is the movement of the planets and of their satellites in the same sense and very nearly in the same plane; if we picture to ourselves in fact all these stars describing from west to east some nearly circular orbits and very little inclined to the ecliptic, while the comets seem to be moved indifferently in every...

Sur La Description Des Formations De . . .

We are interested in nite-time blow-up phenomena for heat equations of the type: @u @t = u+ jujp 1u (1) where u : (x; t) 2 RN [0; T )! R, 1 < p, (N 2)p < N + 2. We rst construct for (1) a solution u which blows-up in nite time T at only one blow-up point x0 2 RN , and describe completely its blow-up pro le (or asymptotic behavior). This construction is based on a priori estimates' technique whi...
