In MkIV: \triangledown is mapped to 0x25BD while nabla is mapped to 0x2207. These are different glyphs. IIUC, the difference in placement is because \triangledown is defined as a mathop (and hence centered on the math-axis) while \nabla is defined as a mathord. Compare: \startformula \nabla T \quad \triangledown T \quad \mathop{\nabla} T \stopformula From what I remember, I was the one who added the mappings for triangledown as a mathop based on, I believe, unicode-math package in LaTeX. I don't understand what all the "triangle operators" are supposed to do. As such, I cannot say whether the wrong placement is due to the wrong font metrics or the wrong mapping (mathop vs mathord) by ConTeXt.

AFAIU, ConTeXt does not use luatex-math.tex. The mappings are defined in char-def.lua. triangle is defined as a mathord (like nabla) while bigtriangleup is a mathop (like triangledown).

Some people use instead $A \Delta B$, but this is not the traditional, nor the correct way, to write this « symmetric difference » of two sets. This is why, I guess, in TeX \triangle is an operator. I have seen also \triangledown as an operator, but I don’t recall the context in which it was used… Regarding the notation \nabla to denote the gradient, and \Delta, to denote the Laplace operator (which by the way can be defined as $\Delta u := \nabla \cdot (\nabla u)$), Mikael Sundqvist gave the correct observations.

Otared points out that the distinction between \triangle and \bigtriangleup comes from plain TeX. plain.tex has these definitions: \mathchardef\triangle="0234 \mathchardef\bigtriangleup="2234 So \triangle is a math ord and \bigtriangleup a math bin.
