发帖数: 4460 | 2 you cannot determine D(t) since f and g are not monotonic.

发帖数: 35 | 5 say stock xyz is traded in two markets that has some time delay D(t) between
them. Let's use f(t) and g(t) to describe the two stock prices.
Real functions f(t) and g(t)
They are not monotonic function, but you may assume f，g are both
continuous.
It is known that g(t)= f(t + D(t))
How to find D(t), also you may also assume D(t) is continuous. |
