The Łojasiewicz exponent of a set of weighted homogeneous ideals

Abstract: a b s t r a c tWe give an expression for the Łojasiewicz exponent of a set of ideals which are pieces of a weighted homogeneous filtration. We also study the application of this formula to the computation of the Łojasiewicz exponent of the gradient of a semi-weighted homogeneous function (C n , 0) → (C, 0) with an isolated singularity at the origin.

“…In 2010 the paper by Tan, Yau, Zuo ([TYZ]) appeared, in which Theorem 1.9 was given in analogous form for n-variables, n > 3, but their proof is false (the proof of their Proposition 3.4 is false). Some results for quasihomogeneous singularities in n-dimensional case were also given by Bivia-Ausina and Encinas ( [BE1], [BE2]).…”
