Thanks a lot Hurky for your explanations .. I guess I am discussing a topic which I don't really understand about . I still am curious why a sphere squished at 2 opposite points would eventually give a singularity , but if squished on all points ( which would result in the formation of a...

I could not understand what you are saying completely . I tried looking up what a covering space was but I didnt understand much in the definitions as they were framed in mathematical language. Anyway from what you have said I assume that a covering space is something like a mapping from one...

Ok .. so going by this you would like to say that the mobius strip has all points as 'singularity' ?? Hence the laws of physics as we know them are no longer valid in this mobius strip. Well I just think we should be open to two different perspectives, or strings of thought . First ...

Yes , I can see that a sheet of paper is not a perfect analogy and the 2 points on 2 different sides are distinct if we look at them as being part of a paper . I also agree with you that if the strip of paper were of 0 thickness and it was transparent also let's say , the 2 points on opposite...

Thank You Hurky and Simpson very much for giving nice examples and helping understand the things . But I disagree that when you go round the mobius strip once , the shape disorients. I feel that by going round the strip once would not leave you in the same place . You have 2 go round the...

Can anyone explain in laymans terms what a Kleins bottle is . I have encountered the definition that it is a non orientable surface , that it is a 2 dimensional manifold in 4 dimensions. I don't have a clue what a non orientable surface is , or what a manifold is . I also don't have any idea...

Thanks very much for the explanation. But there are some doubts which persist for me . You say that I should use the definition of Riemann function on the positive real axis , and extentd the definition for complex numbers . But the thing is that I was only able to find the definition for...

Well , I think I have understood something wrong , because I can think of many examples of functions that are completely differential in a domain , but there exist more than 1 continuation of that function over a larger domain, which is still differentiable. eg. f (x) = 1/ x^3 and f(x) =...

I would like to ask from where did the axioms of ZFC come from in the first place ? Why is it that you consider the axioms of ZFC relevant , but adding a few more axioms to ZFC , just an exercise for set theorists ? I am not a mathematician , and have very limited knowledge of mathematics...

By the way can we not represent the Riemann zeta function over the larger domain with the help of some power series ?

Well , after looking at a couple of places , I came to know that the analytic continuation is a function that has the same value as the given function within the given functions domain , but is defined at points in a larger superset of the original domain too . Also that the analytic function is...

Could anyone tell me what is the Riemann zeta function. On Wikipedia , the definition has been given for values with real part > 1 , as : Sum ( 1 / ( n^-s) ) as n varies from 1 to infinity. but what is the definition for other values of s ? It is mentioned that the zeta function is the...

In the proof , it is not that p1 , p2 , p3 have been replaced by powers of 2 . All that it is saying is that : p1.p2.p3.p4...pn < 2 . (2^2) . (2^4) ... ( 2 ^ (2^n - 1 ) ). This is because it is assuming the theorem to be true for p1 , p2 .. upto pn .

why at all should mn divide f(x) ? consider f(x) = 18 , thus possible values for m and n are 6 and 9 , but clearly 6 x 9 = 54 does not divide 18 , but had m and n been coprime then we would have a completely different answer.

It looks to me like your proof that legendre implies andrica , is implicitly assuming that there are 2 primes between n^2 and (n+1)^2 . But Legendre guarantees only the existence of a minimum of one. If there is only 1 prime bw n^2 and (n+1)^2 , then I am unable to follow how you conclude that...
