摘要:
On the space of bounded sequences, letU(the Césaro operator) be defined byUf(n) =1n∑k=1nf(k). Then iflis any generalized limit,lOUis a Banach limit which also extends Césaro summability. An example is given to show that not every Banach limit extending Césaro summability is factorizable in this way.

摘要:
The theory of polar‐composite polynomials was introduced and quite an extensive study of such polynomials was made by the authors in an earlier paper [7]. In the present paper we give further applications of this theory and obtain a number of results for a completely new variety of composite polynomials which are derived from certain polar‐composite polynomials through iteration. Some important results due to Marden, Obrechkoff and Weisner have also been deduced as consequences of our main theorem here.

摘要:
A pair of complex vector spaces (V,W) is a system if there is aC‐bilinear map fromC2×VtoW. The category of systems is equivalent to the category of modules over a subring ofM3(C). Analogous to rank one torsion‐free abelian groups are rank one torsion‐free systems. Their isomorphism classes are in one‐one correspondence with equivalence classes of height functions. LetR1,R2be two torsion‐free rank one systems. In this paper necessary and sufficient conditions are given in terms of the corresponding height functions for extensions ofR1byR2to be indecomposable. Among other results obtained is the computation of the dimension of Ext(R2,R1) in the case when it is infinite‐dimensional.
