Description
Partial derivatives of Love numbers include Dirac's delta functions, which become infinite at the solid/liquid interfaces. 100% change in liquid density at the mantle-core boundary induces significant variations in Love numbers; 40% change in h2", 20% change in h2', 10% change in l2' and 7% change in k2'. Precise measurements of Love numbers pose a strong constraint on liquid density at the top of core. Taking 1% uncertainty in the liquid core density into account, we expect 0.1-1% uncertainty in Farrel's Green function.
