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.

Self-adjoint Boundary Conditions for the Prolate Spheroid Differential Operator
, 2016We consider the formal prolate spheroid differential operator on a finite symmetric interval and describe all its self-adjoint boundary conditions. Only one of these boundary conditions corresponds to a self-adjoint differential operator which commute ...

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.

On the exponential solution of differential equations for a linear operator
, 1954The present investigation was stimulated by a recent paper of K. 0. Friedrichs 113, who arrived at some purely algebraic problems in connection with the theory of linear operators in quantum mechanics.

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 ...
