Then ϕ(r) satisfies the Bessel equation (0.1) ϕ''(r)+ϕ''(r)/r−ρϕ(r)=0, if x ∈ R^2 or (0.2) ϕ''(r)+(n−1/r)ϕ''(r)−ρϕ(r)=0, if x ∈ R^n ,for n≥ 3. In this thesis, we intend to solve the solutions of (0.1) and (0.2) with n = 3. URI: http://hdl.handle.net/11455/97284 文章公開時間: 2018-08-24 Appears in Collections: 應用數學系所
