Jan 23, 2014 at 10:20 comment added Jaap Eldering @mac: ah, if $E \oplus F$ is the splitting, they use linear map $L$ for a graph description of $F$ wrt. $E^\perp$. Draw this in 2D and you'll see that the norm of $L$ is the cotangent of their angles. In general, $\|L\|^{-1}$ is the tangent of the "usual" angle between $E$ and $F$.

Jan 23, 2014 at 6:12 comment added mac Jaap Eldering: Thank you for your response. I have always been thinking as you do. Maybe its better to consider $v\in E^s(x), w\in E^u(x)$ with $\Vert v\Vert=\Vert w\Vert=1$. But i am somehow confused after studying the paper"On C^1-persistently of homoclinic classes" By "Martin Sambarinho and Jose vieitez". in this paper they have defined the angle between two subspaces in a different way. Is this definition equivalent to yours?
