Singularities of functions with harmonic leading terms of two variables
arXiv:1511.03340
Abstract
We study the classification problem of singularities of function-germs with harmonic leading terms of two variables under the right-equivalence. We study the classification in the cases that the order of function-germs is at most 7. Moreover, we observe that the multiple actions of Laplacian appear for the classifications of such class of function-germs.
