Using the index

People might use i or j or even k for indicies, as such "numbers" are indexed as "num" (notice the lower-case) so a space like Ck is under C_num.

We do subscripts first, so A2i would be under Anum2

Ordering

  1. First come actual numbers.
  2. Next come num terms.
  3. Then come infty (which denotes \infty
  4. Then come letters (upper case)
  5. Then come brackets ( first, then [ then {

For example C_0 comes before C_i comes before C_\infty comes before C_\text{text}

Index

Space or name Index Context Meaning
C_k\text{ on }U C_num_ON
  • (Everywhere)
(SEE Classes of continuously differentiable functions) - a function is C_k on U if U\subset\mathbb{R}^n is open and the partial derivatives of f:U\rightarrow\mathbb{R}^m of all orders (up to and including k) are continuous on U
C_k(U) C_num_(
  • (Everywhere)
(SEE Classes of continuously differentiable functions) - denotes a set, given U\subseteq\mathbb{R}^n (that's open) f\in C_k(U) if f:U\rightarrow\mathbb{R} has continuous partial derivatives of all orders up to and including k on U
