The Impact of the Poland Foreign Trade On Its Real CO2 Emissions
2017
CO2 emissions are a global problem. This means that nothing or very little will change if only particular countries are involved. The purpose of this paper is the attempt to show the real CO2 emissions of the Poland as well as the impact of its trade on CO2 emissions in other countries in the world and in the EU in 2015. This study was conducted on the group of countries that are the major emitters of CO2 in the world including most of the EU members. Actual CO2 emissions were achieved by applying the actual emission factor. This takes into account the transfer of CO2 in export products and services as well as those imported by particular countries. It has turned out that the real CO2 emiss…
Quantum waveguides with magnetic fields
2019
International audience; We study generalised quantum waveguides in the presence of moderate and strong external magnetic fields. Applying recent results on the adiabatic limit of the connection Laplacian we show how to construct and compute effective Hamiltonians that allow, in particular, for a detailed spectral analysis of magnetic waveguide Hamiltonians. We apply our general construction to a number of explicit examples, most of which are not covered by previous results.
