We present here a number of results on some aspects of Kohn-Nirenberg's theory of pseudo-differential operators. We hope that some parts of Kohn-Nirenberg's paper[1] are presented here in a more detailed and explicit form; this could help a larger audience to understand their ideas and methods.

Differential Operators and Differential Modules
2003In this chapter k is a differential field such that its subfield of constants C is different from k and has characteristic 0. The skew (i.e., noncommutative) ring D :=k[∂] consists of all expressions L :=a n ∂ n + ⋯ + a1∂ + a0 dot with n ∈ Z, n ≥ 0 and all a i ∈ k. These elements L are called differential operators.

In this chapter we study a number of well-known differential operators, which are familiar from the studies of basic calculus, using the framework and terminology of the tensor analysis. We study the Hamiltonian ∇-operator, gradient of scalars, divergence of vectors and tensors, curl of vectors, and Laplacian of scalars and tensors.

This chapter covers the mathematical objects: scalar and vector fields, and the three vector differential operators: grad, div and curl. It begins with an overview of scalar and vector fields, followed by the gradient of a scalar field, the divergence and curl of a vector field.

Differential Operators and Regression
2002We give statistical evidence from 28 performances of Schumann’s “Traumerei”, as measured by Bruno Repp [886] that the rhythmic, motivic, and harmonic analyses provided by RUBATO® are shaping structures for the agogical streams. The statistical model is based on regression analysis and realizes shaping of agogics by a second degree linear differential ...
