First of all, I don't know if this is the right place to ask about this. If not, please direct me somewhere I can get more help.
I have to research in the field of special functions with a lie algebra There are some previous titles in this area to clarify what I mean
1) The Lie algebra of ce...
We have two dots $d_1,d_2$ moving on circles $C_1, C_2$ with radii $r_1, r_2$. The circles are moving at speed of $s_1, s_2$. A line is drawn between $d_1$ and $d_2$. When does this line have some segment inside the smaller of the two circles?
There is some code here.
Let $x=(x_1,x_2,\ldots,x_n)$ be an $n$-tuple where $n$ is even In how many ways we can arrange such that exactly half of the
entries are even ?
My attempt is : As we are talking about possible arrangements where order doesn't matter, so we will use combination, not permutation.
So for $n/2 =...
Completeness is an important notion in mathematics. Metric spaces can be complete, a theory can be complete, a logic can be complete, and set of propositional connectives can be complete, and many other objects can be complete.
We tried to remove it already. But completeness keeps coming back.
