Family of curves tangent to a smooth distribution of lines

Click For Summary
SUMMARY

The discussion centers on the existence of a unique family of curves that are tangent to a smooth distribution of lines in R2. A smooth distribution is defined as a set of lines Lp associated with each point p in R2, where Lp varies smoothly with p, forming a smooth subbundle of TR2. The conversation highlights that these lines represent directions at each point rather than straight lines, and it references a fundamental theorem on ordinary differential equations that ensures the existence of integral curves through any point in the vector field.

Hi,
Given a smooth distribution of lines in R2, could we assert that there is a unique distribution of curves such that:
- the family of curves "fill in" R2 completely
- every curve is tangent at every point to one of the smooth distribution of lines

Can you be more precise about what you mean by a smooth distribution of lines?
 
I mean: to each point p in R2 is associsted a line Lp. The family Lp depends smoothly on p. It is somewhat a smooth subbundle of TR2

So can these lines intersect? Or do you mean directions at each point not straight lines in space?
 
Indeed, directions at each point.

A smooth set of directions is called a vector field and I think a fundamental theorem on solutions of ordinary differential equations guarantees an integral curve through any point.
