while h is odd, meaning the left hand side of neither equation is divisible by 4. thus when \(m=1\) , s is the largest set of rationals over which the sum defining \(g_2(a_mq^\frac{1}{2b_m};q^\frac{1}{2})\) terminates. for \(m=3\) , we have \(b_3=3\) so ...
On the other hand, the violation of the KSS bound due to the breaking of the translational symmetry has a more fundamental nature. In this case the shear viscosity does not have the usual hydrodynamic meaning but might be interpreted as the rate of entropy production due to a strain [31,32...
