pat_bnd
provides the Pataki inequalities for given beta
and n
.
pat_bnd(beta, n)
beta | Dyson index specifying the underlying (skew-) field:
|
---|---|
n | size of matrix |
The output of pat_bnd
is a list of five elements:
d
: ambient dimension of corresponding Euclidean space,
given in terms of beta,n
by n+beta*choose(n,2)
k_low
: function returning the lower bound for index k
, given r
k_upp
: function returning the upper bound for index k
, given r
r_low
: function returning the lower bound for index r
, given k
r_upp
: function returning the upper bound for index r
, given k
