Let $x_1,x_2,…,x_n$ be zero mean Gaussian random variables with covariance matrix $\Sigma=(\sigma_{ij})_{1\leq i,j\leq n}$.
Let $m$ be the maximum of the random variables $x_{i}$ $$ m=\max\{x_i:i=1,2,\ldots,n\} $$

Finding the inverse of a rational function.
Im solving to find the inverse of f(x)=(2x+1)/(x-1) and ran into a snag.
heres what i did so far...
1. f(x)=(2x+1)/(x-1)

Induced character for non-injective homomorphisms

Any group homomorphism $\phi\colon H\to G$ gives rise to an induction/restriction adjunction between $G$-representations and $H$-representations: $$ \hom_G(\phi_! M, N) \cong \hom_H(M, \phi^* N) $$

A 3D-sphere mapping?
Hello all,
On the 2Dsphere there are:
- 1 parallel.
- 2 meridians.
In this case:
- A 2Dsphere is mapped with 8 spherical triangles (polygon).
- A polyhedral simplification is octahedron.
On the 3Dsphere there are: (I suppose)
- 1 parallel.
- 2 meridians.
- 3 Hyper-meridians.
In this case, the 3Dsph... | {"url":"http://hddb.teamikaria.com/forum/viewtopic.php?p=14547","timestamp":"2014-04-18T23:15:23Z","content_type":null,"content_length":"19987","record_id":"<urn:uuid:cd07fb97-d2b8-42e6-b791-9fd791129451>","cc-path":"CC-MAIN-2014-15/segments/1398223207985.17/warc/CC-MAIN-20140423032007-00446-ip-10-147-4-33.ec2.internal... |
