Combined Theoretical and Experimental Study of Refractive

The refractive index, n, defined as the ratio of the speed of light in vacuo c 0 to the speed of light in the material c, is one of the most fundamental properties of pure liquids and their solutions and has been measured and interpreted since the early 19th century. This optical property can be measured for a small amount of sample in wide ranges of temperatures

2019.8.1  The proof consists in observing that any least energy solution has Morse index equal to 1 (this is always true in any Ω ⊂ R N, N ≥ 2) and then in showing that, when the domain is convex and N = 2, any Morse index 1-solution to (1.1) is nondegenerate. This gives the uniqueness of the branch of Morse index 1-solutions.
