The present study has evolved out of a limited field work during a short visit to Oman. It is an attempt to record more detailed data on the plant communities and their habitat features in three sectors of northern Oman. ...
Point-Wise Summability Of Fourier Series And Its Related Series In The Norlund Sense
(
Qatar University
, 1985 , Article)
In this note we consider the point-wise summability of Fourier series in the Norlund sense by extending a theorem of Lebesgue [ 6 ] . We also consider analogous theorems of our extension to derived Fourier series, and ...
