If you consider 2d picture - similar measure on the space of function f(x,y) it will not live on continuos paths but on distributions ! I guess it is related to the "regularization, renormalization" which is present in QFT, but absent in QM | |
| Jan 27, 2012 at 10:30 | comment | added | Alexander Chervov | @Shu thanks for thanks :) Shame on me I forget why it is on continuos paths ... As I remember it was simple - the same as why Wiener measure is on them... I'll try to remember. But actually the measure I mentioned is "more or less" standard Wiener measure ... | |

| Jan 26, 2012 at 19:57 | comment | added | shu | @Alexander Chervov, indeed, this measure works formally. I want to make it rigourous. It is not even clear for me that its support is the contious path. | |
| Jan 26, 2012 at 17:39 | comment | added | Alexander Chervov | Periodic function can be decomposed to Fourier Series - on each component you have Gaussian measure scaled by "n" - so we get measure on periodic paths... Is there something wrong with it ? | |
