Abstract: Abstract In the context of the new definition of convergence of a double sequence and double series introduced in Chap. 5 , we define the Nörlund, the Weighted Mean, and the $$(M, \lambda _{m,n})$$ or Natarajan methods for double sequences and double series and study some of their properties.
