We study the functions on the punctured n-dimensional sphere having zero integrals over all admissible “hemispheres.” We find a condition for the point to be a removable set for this class of functions and show that the condition cannot be dropped or substantially improved. 相似文献

A laminar subsonic flow of CO-He-N2 mixture in an axisymmetric channel with glow discharge is investigated. The actual flow diagram is modeled on the basis of a system of narrow-channel equations. The results of the calculations are compared with the experimental data. The possibility of applying a one-dimensional system of equations is analyzed.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 6, pp. 114–119, November–December, 1985.The authors wish to thank B.

We study functions on a sphere with a pricked point having zero integrals with a given weight over all admissible “hemispheres”. We find a condition under which the point is a removable set for such a class of functions. We show that this condition cannot be dropped or substantially weakened. 相似文献
