Following on from the last blog, can we show ?
Assume a constant, exists such that , could give us this ?
Edit: Professor Rubin (see comments) tells me that, as I feared, what follows is not supportable:
Now, and this is the bit I have most doubts over, as and then and and assuming then we are left with .
Hence and therefore , the constant we are seeking.
But there are a lot of assumptions in there: anybody able to tell me how valid they are?
