why quintics are Calabi-Yau?
I find the question "Why quintics are Calabi-Yau" rather cryprtic. Would you mind to give some more information? |

Adjoint operator of a Convex operator is convex
I didn't come across convex functions with values in an ordered normed space yet, but well, the adjoint is linear and this still implies convexity. |

Modulus of of continuity of a convolution operator with respect to Wasserstein metric
What are $dx|\theta$ and $x|\theta$? For $x-\theta$ to make sense, you that $\Theta$ is not just a metric space but has a linear structure. Or do you consider it to be a topological group? |

how to complete arbitrary basis knowing 2 orthonormal vectors of Rd (d > 2)
Theoretically? Then it doesn't matter, completion exists. Practically? Choose random vectors. Anyway: Not suited here, better for math.SE. |

To nit-pick a bit: By this definition also 1 is prime. |

An Interesting Optimization Problem
Looks more like a (discrete) optimization problem than a number theory problemâ€¦ |

“Paradoxes” in $\mathbb{R}^n$
Right - the cube is actually a simpler example than the simplex... |

Why distributions as functionals?
@Alexander Shamov: That's some point... But well, "average" sounds pretty linear to me. More practically: A light sensor is basically collecting all the light that hits it and hence, measures the average (in the sense of arithmetic mean) light in that region. I do not know enough about other sensors but linearity sounds very reasonable to me. |

What is the best way to optimize this matrix equation
Is that the same problem that is solved by this MATLAB routine mathworks.de/de/help/stats/procrustes.html? |
