existence of a solution to equation (7) and hence our differential equation (1). Uniqueness There are several ways to prove the uniqueness of the solution of the initial value problem (1). None of them are difficult. We work in the interval [0, β] defined above. Say U~(t) and ~V (t) are both solutions. Let W~ (t) := U~(t) − V~ (t).

Global Existence of Solutions. We assume that each admissible set of initial data for Δ is consistent with a solution defined on all of V.74 Uniqueness of Solutions. If Φ and Φ ′ are solutions that agree in the initial data that they induce on an instant ∑ ⊂ V, then they agree at any point x ∈ V at which they are both defined.

09.01.2022 · The recent paper considers a hydrodynamic flow of compressible biaxial nematic liquid crystal in dimension one. For initial density without vacuum states, we obtain both existence and uniqueness of global classical solutions. While for initial density with possible vacuum states, both the existence and uniqueness of global strong solutions are given.
