Let f : (Cn, 0) → (C, 0) be a semiquasihomogeneous function. We give a formula for the local Łojasiewicz exponent L0(f) of f, in terms of weights of f. In particular, in the case of a quasihomogeneous (QH) isolated singularity f, we generalize a formula for L0(f) of Krasiński, Oleksik and Płoski from 3 to n dimensions. This was previously announced in the paper [19] of Tan…
