Abstract:
Let f be a definable C1 function defined in a neighborhood of the origin in Rn. Using Lagrange specialization and the deformation to the normal cone we describe geometrically the space of limits at the origin of secant lines and gradient directions of f, understood as a subset of Pn−1×Pn−1.
We apply this description to study the gradient flow of f.
