This identity is derived from the divergence theorem applied to the vector field F = ψ ∇φ while using an extension of the product rule that ∇ ⋅ (ψ X) = ∇ψ ⋅X + ψ ∇⋅X: Let φ and ψ be scalar functions defined on some region U ⊂ R d, and suppose that φ is twice continuously differentiable, and ψ is once continuously differentiable.
There followed a long silence—Green always found writing difficult—which was broken in 1972 with the appearance of a volume titled The Power of Sergeant Streater. Published as a novel, it is in fact three interrelated novellas each illustrating what Frank Tuohy identified as Green’s principal theme: ‘the relationship of an older man ...

THE INDEPENDENT’S BANNED BOOKS WEEK: ‘Looking For Alaska’, Green’s 2005 debut, has been a target of book banning efforts for at least 15 years. Clémence Michallon speaks to the author ...
In his paper "The S-Matrix in Quantum electrodynamics", [1] Dyson derived relations between different S-matrix elements, or more specific "one-particle Green's functions", in quantum electrodynamics, by summing up infinitely many Feynman diagrams, thus working in a perturbative approach.
As a House member, John Curtis, R-Utah, exhibited a willingness to buck his own party. Now the senator-elect who is set to take the seat being vacated by retiring Mitt Romney, said he’s not ...
