Parametrization simple irreducible plane curve singularities in arbitrary characteristic
We study the classification of plane curve singularities in arbitrary characteristic. We first give a bound for the determinacy of a plane curve singularity with respect to pararametrization equivalence in terms of its conductor. We then define the notion of parametrization modality for plane curve singularities. Finally, we revisit Mehmood-Pfister’s classification of parametrization simple plane curve singularities which are irreducible by giving a concrete list of normal forms of equations and parametrizations. In characteristic zero, the classification of parametrization simple irreducible plane curve singularities was achieved by Bruce and Gaffney
Energy Consumption and Economic Growth: Evidence from Vietnam
The importance of non-renewable, renewable and sustainable energy sources and energy
consumption in the economic development strategy of a country is undeniable. The purpose of
the paper is to investigate the impacts of energy consumption on the economic growth of Vietnam
during the 1980-2014 period. By applying the Autoregressive Distributed Lag (ARDL) model
of Pesaran et al. (2001),
