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.
| 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 |
| 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 |
