How we solve Diophantine equations
... 2 has an integer solution if and only if it has a real solution and solutions modulo all prime powers. In other words, the obvious necessary conditions are also sufficient. We say that equations of degree 2 satisfy the Hasse principle. This reduces the decision problem to a finite computation, since ...

Propagation of ULF waves through the ionosphere: Inductive effect
... Nishida, 1964). At middle to low latitudes, the shear Alfvén wave mode can form field line resonances (e.g. Miletits et al., 1990; Waters et al., 1991; Ziesolleck et al., 1993), so that the resonant frequency increases into the Pc3 (20–100 mHz) range with decreasing latitude. A formulation which in ...
