Talk:Invariance theorem

From Wikipedia, the free encyclopedia

Although not problematic to those familiar with the diatype, at its face, the main connective of this formula is ambiguous:

C(x)=C_U(x) \leq C_M(x) + c.

An explanation of the meanings of C(x), C_U(x) and C_M(x) will also be needed. These explanations will likely be found in Li and VitanyĆ­'s book. Since I don't have it handy, can anyone help clarify this theorem?

Also, in my opinion, any math article concerning a theorem should have (1) an informal statement of the theorem, (2) why it is significant, (3) an informal sketch of one of its proofs, and (4) eventually show a more formal proof. Vonkje 14:06, 23 July 2005 (UTC)
