As time goes on, I grow more disillusioned with quantum field theory.

Hiding certain user-defined functions in front-end autocompletion Do you mean I am supposed to hope the user doesn't start writing xxx...? |

Hiding certain user-defined functions in front-end autocompletion Oh sorry, yes; I meant the autocompletion. I will make edit. But I also don't know how to write a package... |

How to identify patterns in a tensor-polynomial and replace appropriate symbol? Yes, this is very short indeed! And, yes, the power will always be a numeric integer; never symbolic. |

How to identify patterns in a tensor-polynomial and replace appropriate symbol? This is my favorite! I am especially impressed by your correct guess that a constant should yield f[{}]. Your code and the accompanying explanation was clear enough for me to be able to tweak and embed it into my program. One question/observation: this code seems to work correctly even when the input polynomial is not expanded out in full: for example $(r_i+q_i)(r_j+q_j)$ works as intended. At what point does Mathematica know to expand everything out? |

How to set a TraditionalForm output for a symbol This is certainly a very short piece of code, but I've never seen many of the symbols/functions in here. I'd have to investigate! |

How to set a TraditionalForm output for a symbol Yes, you are right; Jens' answer doesn't lead to extraneous parentheses. And, yeah -- I thought your answer was more economical because it took 'fewer lines.' Those are my newbie instincts showing up. |

How to set a TraditionalForm output for a symbol Oh, I am just saying that the result of the example in my comment above is: $3\big(B_{0011}(s,m0,m1)\big)$, and the outer parenthesis is extraneous. |

How to set a TraditionalForm output for a symbol This answer is very economical, but the problem is that if the pvB function appears in a larger expression, an unneeded pair of parenthesis is added around it. Try TraditionalForm[3 pvB[2,4,x,s,m0,m1]], for example. How should I remove it? |
