Ravi Jhaveri MD,Yvonne Bryson MDIn Section 2.6 we defined the differential operator .,.and its formal adjoint .,.where the coefficients a.. are infinitely differentiable functions, . is a distribution, and . is a test function. These operators are related by the equation.This means that the action of . on φ is equivalent to the action of . on the test function . =.*..
