 May 8 comment From $\dim A\leq \dim B$, can we conclude that $A\subseteq B$? Oh how can i be such an ignorant? thanks sir May 8 comment From $\dim A\leq \dim B$, can we conclude that $A\subseteq B$? Take spaces A and B of non col linear straight lines passing through origin in $R^2$ though $dim A = dim B$ ,but we cant conclude that A⊆B. They have only one point in common that is zero vector. Am i right sir? May 8 comment From $\dim A\leq \dim B$, can we conclude that $A\subseteq B$? Straight lines are of dimension 1 in $R^2$ . It seems as my conclusion is wrong.

May 8 comment Proving two results about the spectral radius Can't i apply these theprems on Banach space operators? May 7 comment Proving two results about the spectral radius It's general result. My main concern is can we apply these theorems in Banach space as well?
