Brownian motion random walk with decaying steps

69 Views Asked by At

Is there any work on Brownian motion with decaying steps?

For example variations such as:

(1) a random walk in which nth step is $+\frac{1}{\sqrt{n}}$ or $-\frac{1}{\sqrt{n}}$ length of equal probability.

(2) a random walk where nth step has possibilities of $+\frac{1}{\sqrt{n}}, 0, -\frac{1}{\sqrt{n}}$ each of 1/3 probability.

I am interested in finding the effect - if any - such variations have on the growth rate, which for +/-1 is given by:

$$ \limsup_{n \to \infty} \frac{S_n}{\sqrt{2n\log\log n}} = 1 $$

Intutively I feel, the first modification should result in: $$ \limsup_{n \to \infty} \frac{S_n}{\sqrt{2\log\log n}} = 1 $$ and second may result in: $$ \limsup_{n \to \infty} \frac{2S_n}{3\sqrt{2\log\log n}} = 1 $$ but I would like to look at some proofs in this area.
