There is an asymmetric tensor-like binary product operation on rings, and the notation for it is informed by both the notation for semi-direct product \rtimes
and that for tensor product \otimes
. It looks like a tensor product, with the arc of the surrounding "O" missing between the lower-left leg and upper-left legs of the central "X". Here is a photo of the symbol in context, hand-drawn using an iPad:
As far as I know it is so far exclusively handwritten. How can I create a glyph for this operation in LaTeX? I'd like to call it \rtensor
. I have the sense that the easiest way to do this is to somehow modify the glyph for \otimes
by removing an arc from one side, since I want it to be the same size and have the same spacing properties. But I don't know how to proceed.
Can someone help me typeset this symbol?
Best Answer
Here is an easy "design-your-own" TikZ solution.
Advantages: Easy. Nicer corners compared to clipping.
Disadvantage: Not truly the exact spacing of
\otimes
. But close.Code:
Update: If it's important to get the spacing for
\rtensor
to be exactly the same as\otimes
, you can redefine\otimes
. Use\let
to retain the original\otimes
definition if you wish.
