Query: Singularities of functions with harmonic leading terms of two variables   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.
