Hi, Let S^1 be the unit circle in the complex plane, and let End(S^1) be the group of self-homomorphisms of S^1,(with the topology inherited from (S^1)^(S^1),...
I am trying to get some a priori estimates for Cahn-Hilliard equation. u_t + {\Delta}^2 u = \Delta f(u) where \Delta is the Laplacian. f(u) = \gamma ( u^3 -...

Thanks a lot for the clarification, that was very helpful. Does the anwer suggest that, for certain class of functions (with more restrictions than bounded)...

Do you know where i can find a proof for the following statement? Cd the one dimensional cantor set with 0 <d <1/2.Then l(D(Cd))>0 iff d >=1/3.Also in that...
I have a simple qn it would be great if someone cared to answer this why is (0,1)x(0,1/2)x(0,1/3)x(0,1/4)x.........(0,1/n)x........ not(?) an open subset set...
nice to meet you.. you are not mentiond that what topology you considered on R infinity. you have to mention that either box topology or product topology or...
I guess for box topology it is trivially an open set (because the way open sets are defined there ) Why is it true/not true for product topology ? Thanx for...
It sounds more like an exercise: If one look on Cd X Cd, then D(Cd) is the diagonal projection of the set. But on the other side it is a Cantor type ...

hi, its not open in product topology becos the basis for product topology consists of products of open sets (U_1, U_2,...) where U_i=R except for finitely many...

Hi, Let G be a LCA group, and T is an one to one continuous homomorphism on G. (T is not necessary onto) when T is open? in fact when G is homeomorphic to...
