Analogies Between Ballistic Electrons and Electromagnetic Waves,nger equation and the Helmholtz equation, i.e., the time-independent form of Maxwell’s equations. Electrons in bulk semiconductors or heterostructures do not behave like waves, and thus cannot be described by the Schrödinger equation unless:高度表 发表于 2025-3-27 15:46:55

Teemu Pulkkinen,Petteri Nurmialar curvature: this should happen exactly when there are no ..-valued obstructions coming from Dirac operators. When the universal cover does not have a spin structure, the conjecture says there should always be a metric of positive scalar curvature, and we prove this if the dimension is ≥5 and if蛛丝 发表于 2025-3-28 09:22:00
Klaus F. Riegele Verordnung (EWG) Nr. 1408/71 und deren Reformbedürftigkeit und -perspektiven. Die zentrale Frage ist dabei, ob es gelungen ist, sowohl die Freizügigkeit als auch mitgliedstaatliche Interessen und Kompetenzen in angemessener Form zu berücksichtigen und in Einklang zu bringen.
