Negative probability means that stochastic matrix and Markov chain theory breaks down. Not to mention the current underlying mathematics..

Wigner function is not a probability distribution, its values are not probabilities at all. Wigner function is just a different way of representing the wave function.

Did someone say that Wigner function was a negative probability?Wigner function is not a probability distribution, its values are not probabilities at all. Wigner function is just a different way of representing the wave function.

Yes, Collector did: "why the negative probs in the Wigner quasi-prob-distribution?"

This is the section where I stopped reading the article. I thinks if Feynman knew (or used) how integers (+, -) were constructed from the natural numbers (+) there might have been some hope, mathematically speaking.

Now it's "let's assume neg probs exist? Too much name dropping.

Here is a discussion and critique (by John Baez?) from a mathematical perspective on negative probabilities. Worth a read

*Unsurprisingly, the clearest writing about negative probabilities that I’ve found is by Feynman:*

It is a culture-shock that people still believe in these things, like the tooth fairy.

I submitted a paper recently where the reviewers got upset because I criticized the use of negative probabilities.

Why so positive to negative probabilities?

A1: Do you remember the restaurant where we first met?

B: Yes, how could I forget! The one next to Piazza San Marco.

A2: It was actually in Rome.

B: Opss... you're name isn't Adam, is it?

A2 is a negative information from the point of view B. People use it for lying and deception or just being wrong

Are u describing the meeting of Rome-o and Juliet, or Adam and Eve? actually written by B!

"I just hope they apologised to you. "

Not yet, but you cannot have probabilities without time? so probably in the future?

Romuliet is a good example too: he thinks she's dead but she isn't, she thinks he isn't dead but he is, they are both dead. Negative information was what killed Romeo and Giulietta.Are u describing the meeting of Rome-o and Juliet, or Adam and Eve? actually written by B!

yes dead and alive, the immortal atoms, one of my favorites from Romeo and Juliet:

"Drawn with a team of little atomies

Athwart men's noses as they lie asleep"

"Who shut their coward gates on atomies"
