On the other hand, $ abla^2 f$ seems to be used here in an unusual way, namely to denote the Hessian (the matrix of all second order partial derivatives), $(\partial^2 f/\partial x_i \partial x_j)_{i,j=1}^n$. (The usual meaning of $ abla^2 f$ is the Laplacian, $\partial^2 f/\partial x_1^2 + \ldots + \partial^2 f/\partial x_n^2$.)A pattern, character or image used instead of words. Example: the recycle symbol. Another example: "+" is the symbol for "plus". Symbols in Geometry. Illustrated definition of Symbol: A pattern, character or image used instead of words. increment: An increment is a small, unspecified, nonzero change in the value of a quantity. The symbol most commonly used is the uppercase Greek letter delta ( ). The concept is applied extensively in mathematical analysis and calculus.

A mathematical concept is independent of the symbol chosen to represent it. For many of the symbols below, the symbol is usually synonymous with the corresponding concept (ultimately an arbitrary choice made as a result of the cumulative history of mathematics), but in some situations, a different convention may be used.Scott Pakin, The Comprehensive L a T e X Symbol List, 2017.

This is a summation of the expression 2 n − 1 for integer values of n from 1 to 3 :In mathematics. In mathematical formulas, the ± symbol may be used to indicate a symbol that may be replaced by either the plus and minus signs, + or −, allowing the formula to represent two values or two equations. [8] If x2 = 9, one may give the solution as x = ±3. This indicates that the equation has two solutions: x = +3 and x = −3. ….
