My main activity is in number theory of integral positive ternary quadratic forms. This began through years of working with Irving Kaplansky. Much of his unpublished writing on quadratic forms can be found as pdfs at
http://zakuski.math.utsa.edu/~kap/forms.html
and about Lie and Jordan superalgebras at
http://zakuski.math.utsa.edu/~kap/superalgebra.html
One of my own email addresses can be found easily using the search feature at
http://www.ams.org/cml
and just putting in my last name

Why Adrian Vasiu did not get the fields medal?
I think the trouble is that Vasiu's supporters would not reveal their real names. |

A conjectured formula for Apéry numbers
@Gerry, yes, I was going to mention him and found that I could not be sure of the spelling. It seems quite a good book, I will probably buy it, I don't buy many books these days. |

A conjectured formula for Apéry numbers
Just a suggestion, Wadim Zudilin quit MO some time ago; he is a CARMA at Newcastle, Australia. His sort of thing. I write to him with questions occasionally, he sends brief answers or references. Has a new book with Shallit and Borwein cambridge.org/us/academic/subjects/mathematics/number-theory/… |

For integers $a \ge b > 1$ is $f(a,b) = a^b + b^a$ injective?
No real matter; the best I could do up to $10^{1000}$ was $a=46,b=154,c=7,d=303,$ both about $1.16066 \cdot 10^{256}.$ Ratio about 1.000000104, relative error about 1 part in 9,574,939. |

@TimothyChow, it's a pity. Very impressive to see thousands of these huge numbers, 100 digits long but no more than four agree. |

@GerryMyerson, thanks, that was the other side of the question |

@XL_at_China, no idea. What is your background? |

Negative impact of wrong or non-rigorous proofs
Deane, I don't know. There are many other examples at the same question, maybe some will be helpful. Mine was a gap that was fixed, most of those answers are things that remained wrong. |
