comment What type of non-differentiable continuous paths contribute for the path integral in quantum mechanics
Thanks. I updated my question with some additional comments. Do you know of a good reference which discusses the countable product of standard gaussians you describe above?

comment What type of non-differentiable continuous paths contribute for the path integral in quantum mechanics
Thanks for the reference. I have updated my question based on what I understood from there. It clarifies my question about the Brownian motion but I am still confused why the contributing paths have $\alpha < 1/2$.

comment Lax-Pair for principal chiral model
Thanks for your great explanation. By the way, is there any advantage to including a minus sign in the exponent of the Wilson line? It seems like it would be easier to define it without the minus sign in which case the derivation would go as below.

comment What sets AdS radius of the Vasiliev dual to the O(N) vector model?
That makes some sense. In the free O(N) model we effectively have $\lambda = 0$. Then the equation $R/l_s = 0$ can be satisfied for any value of $R$ since $l_s \to \infty$ in the tensionless limit as you say. So I think the answer is that all values of $R$ are equivalent for the O(N) model.

comment Gauge fields and strings: Loop equations
Thanks for your answer. I'm not quite sure I fully understand it yet. In the meantime, however, I think I have a more pedestrian explanation (see below).
