WebWe study normal forms of germs of singular real-analytic Levi-flat hypersurfaces. We prove the existence of rigid normal forms for singular Levi-flat hypersurfaces which are defined by the vanishing of the real part of complex quasihomogeneous polynomials with an isolated singularity at $$0\in \mathbb {C}^2$$0∈C2. This result extends previous results of Burns … Web25 de fev. de 2024 · How do I convert a Pandas dataframe from a 'frequency table' format to a flat dataframe format and back again using idiomatic Python?
