%X Without the successful work of Professor Kakutani on representing a unit vector space as a dense vector sub-lattice of
in 1941, where X is a compact Hausdorff space and C(X) is the space of real continuous functions on X. Professor M. H. Stone would not begin to work on ˇ°The generalized Weierstrass approximation theoremˇ± and published the paper in 1948. Latter, we call this theorem as ˇ°Stone-Weierstrass theoremˇ± which provided the sufficient and necessary conditions for a vector sub-lattice V to be dense in
. From the theorem, it is not clear and easy to see whether 1) ˇ°the vector sub-lattice V of C(X) contains constant functionsˇ± is or is not a necessary condition; 2) Is there any clear example of a vector sub-lattice V which is dense in
, but V does not contain constant functions. This implies that we do need some different version of ˇ°Stone-Weierstrass theoremˇ± so that we will be able to understand the ˇ°Stone-Weierstrass theoremˇ± clearly and apply it to more places where they need this wonderful theorem.
