Properties of discrete fractional calculus in the sense of a backward difference are introduced and developed. We introduce a more general discrete fractional operator, given by convex linear combination of the delta and nabla fractional sums. We show that two recent definitions of discrete nabla fractional sum operators are related. Since we need to know how steep it is as well as which direction it faces, it is a vector property. The differential operator del, also called nabla operator, is an important vector differential operator. Another example is the algebraic operator $\nabla^2$. Exponential laws and a product rule are devel-oped and relations to the forward fractional calculus are explored. We introduce three field operators which reveal interesting collective field properties, viz. Then '&(%) 51. It seems that < H (k1 (n-k)) (X;t), h 1 n > is a q,t analog of the numbers (k+1) k-1 (n) (n-k). The del operator. 52 LECTURE5. A quantum-mechanical operator $\Aop$ does not work on an algebraic function, but on a state vector like $\ket{\psi}$. ... which is called “del” or “nabla”. Properties of the Laplace transform for the nabla derivative on the time scale of integers are The nabla symbol ∇, written as an upside-down triangle and pronounced "del", denotes the vector differential operator. As particular cases, results on delta and nabla You can see why the same word is used in both cases, but you should keep in mind that the two kinds of operators are different. Menu. nabla Let f : ℝ n → ℝ be a C 1 ⁢ ( ℝ n ) function , that is, a partially differentiable function in all its coordinates. In the first lecture of the second part of this course we move more to consider properties of fields. It is denoted by the symbol \(\Delta\): It is … We illustrate this idea with proving power rule and commutative property of discrete fractional sum operators. For some more of the amazing properties of this operator see the references below: We define a vector operator $\vec{\nabla}:=\vec{e_x}\frac{\partial}{\partial x}+\vec{e_y}\frac{\partial}{\partial y}$. Obtaining such a relation between two operators allows one to prove basic properties of the one operator by using the known properties of the other. It appears frequently in physics in places like the differential form of Maxwell's equations. This is the del operator (or Nabla operator) in two dimensions. ... Properties of differential operators. A defintion of the operator nabla on symmetric functions. Fundamental properties of the new fractional operator are proved. The scalar product of two operators nabla forms a new scalar differential operator known as the Laplace operator or laplacian. The symbol ∇ , named nabla , represents the gradient operator , whose action on f ⁢ ( x 1 , x 2 , … , x n ) is given by Insights Blog-- Browse All ... What you're talking about is called the Advective or Convective operator and describes the change in a property due to flow of continuous media (in Fluid Mechanics anyway).
