Answer to: Use Green's Theorem when \vec F(x, y) = (e ^x - x^2 y) \hat i + (e ^y+ xy^2 ) \hat j and C is the circle x ^2 + y^2 = 25 oriented...
many-body Green's functionscorrelation functionscomplex eigenvaluesIn this paper, an extended spectral theorem is given, which enables one to calculate the correlation functions when complex eigenvalues appear. To do so, a Fourier transformation with a complex argument is utilized. We treat all the ...
The spectral theorem of many-body Green's function theory when there are zero eigenvalues of the matrix governing the equations of motion Spectral theorem of many-body Green's function theory when there are zero eigenvalues of the matrix governing the equations of motion [J]. Phys Rev B,......
Notice that the limiting rate does not depend on the choice of the threshold h, as is evident from the way that the first equality is established by bringing exp(−γh) into play. Furthermore, the limit is often independent of the initial conditioning information. We apply these ...
