ASCII and Vector Calculus Operators

Some users may have trouble entering unicode characters like ⋆ or ∂ in their development environment. So, we offer the following ASCII equivalents. Further, some users may like to use vector calculus symbols instead of exterior calculus symbols where possible. We offer support for such symbols as well.

ASCII Equivalents

Unicode	ASCII	Meaning
∂ₜ	dt	derivative w.r.t. time
⋆	star	Hodge star, generalizing transpose
Δ	lapl	laplacian
∧	wedge	wedge product, generalizing the cross product
⋆⁻¹	star_inv	Hodge star, generalizing transpose
∘(⋆,d,⋆)	div	divergence, a.k.a. ∇⋅
avg₀₁	avg_01	average values stored on endpoints of edges

Vector Calculus Equivalents

Vec	DEC	How to enter
grad	d	grad
div	∘(⋆,d,⋆)	div
curl	∘(d,⋆)	curl
∇	d	\nabla
∇ᵈ	∘(⋆,d,⋆)	\nabla \<tab\> \^d \<tab\>
∇x	∘(d,⋆)	\nabla \<tab\> x
adv(X,Y)	∘(⋆,d,⋆)(X∧Y)	adv
