@rehband would you like to buy a book that teaches you how to finish this one without pen and paper? $$\int_0^1 \frac{1+2t}{1+t+t^2} \sum_{k=1}^{\infty} t^{3^k} \ dt=1-\gamma$$
@Alizter Yes, I can, but I cannot share at the moment. I have a paper with another mathematician where there is a trick used that also works there. (I need to check is that paper was published or not ...)
Let me put it this way: in American English, there is no distinction between the verb and the noun - both of them are "practice". In British English, there is a distinction.
@sawarnik In American English, the verb and noun are both practice. In British English, the verb is practise and the noun is practice. Thank you for trusting in me.
Hi guys, apologies if you regard this as spam, but i'd be grateful if someone could take a look at this: http://math.stackexchange.com/questions/983125/primes-is-in-p-page-4-why-is-xa-fracnp-equiv-x-fracnpa-im
@Alizter I think you misunderstood my point. That article was done by me and him, and so far I received no feedback if it was published or not. I can only tell you all the papers that are about to be published are simply mind-blowing, you need to see them once in life. Let's wait for reality ... (until they are published)
@Jasper Loy , it means when your happy with what you have in life and give thanks for it, good comes to you :) maybe in this birth or next birth :) (Buddhism)
@Sawarnik It's in a universe that you can't see from your eyes. You have to meditate, when I meditate I see my soul in a different location that I call Zupras
@JasperLoy I imagine that day like that day when some mathematicians will come together and study my book as some studied the Galileo work before, ready to burn me alive at the end ... :-)))))))))))))))
Is it possible to find a base of $M_n(\mathbb{R})$ that only has non diagonalisable matrices ?
I'm looking for a rather easy example, or a proof of the (non-)existence.
@Chris'ssis yes... I was just going to ask about the $n=2$ case after seeing the question on chat, then I see that it is covered in you comment to my answer.
