Green's first identity proof
WebMay 15, 2016 · Recall Green's First Identity: ∫ Ω v Δ u ( d Ω) = ∫ ∂ Ω v ( ∇ u) n → d ( ∂ Ω) − ∫ Ω ∇ u ∇ v ( d Ω) Which requieres u ∈ C 2 ( Ω) and v ∈ C 1 ( Ω). So the question is simple: Does this apply to weak derivatives? i.e. Can we weaken the conditions given to be u ∈ H 2 ( Ω) and v ∈ H 1 ( Ω)? http://www.translawdc.org/resources/maryland-guide

WebThe Greens reciprocity theorem is usually proved by using the Greens second identity. Why don't we prove it in the following "direct" way, which sounds more intuitive: ∫ all space ρ ( r) Φ ′ ( r) d V = ∫ all space ρ ( r) ( ∫ all space ρ ′ ( r ′) r − r ′ d V ′) d V = ∫ all space ρ ′ ( r ′) ( ∫ all space ρ ( r) r ′ − r d V) d V ′

In mathematics, Green's identities are a set of three identities in vector calculus relating the bulk with the boundary of a region on which differential operators act. They are named after the mathematician George Green, who discovered Green's theorem.
