Abstract: | Existence of a regular unimodular triangulation of the configuration
, where + is the collection of the positive roots of a root system
and where (0, 0,...,0 ) is the origin of
, will be shown for = B
n
, C
n
, D
n
and BC
n
. Moreover, existence of a unimodular covering of a certain subconfiguration of the configuration A
n+1
+ will be studied. |
