发帖数: 102 | 1 OK I was not being precise. But I think the OP was asking about the same
fixed point.
The concept of transversality in differential topology is the following: Two
submanifolds M, N of the manifold W are transversal at x if
TxM + TxN = TxW
the sum is in the sense of vector subspace. This is somewhat different from
the naive sense of transversality. If two submanifolds intersects at at a
point, then the transversality condition is the same as having "nonzero
angle".
As I explained, the intersec... 阅读全帖 |

This is not true in general!
None of you guys get it straight. The correct statement is that
Given a continuous-time dynamical system, the stable and unstable manifolds
of the SAME fixed point can never intersect transversally at any location
other than the fixed point itself. The meaning of "transversal intersection"
is exactly the same as its usual meaning in differential geometry.
For a continuous-time dynamical system (dimension 3 or higher), there can be
transversal intersections, for exam... 阅读全帖 |

MI include NSTEMI and STEMI.
Both unstable angina and NSTEMI present with ST depression on ECG, but
cardiac enzymes are normal in unstable angina and elevated in NSTEMI.
Thrombolytic therapy is beneficial in patients with STEMI, but is not
effective in UA or NSTEMI and may be harmful!
Percutaneous coronary intervention can be used in all acute coronary
