Notations for pairs of partition vectors and majorisation.
Positive integer (natural number) to be partitioned.
Discrete
partition vectors (column vectors) with nonnegative integers ui and vi as components ().
They are used as pair of partition vectors to be compared with respect
to majorisation and discrete vector catalysis.
The following conventions are
assumed. If a pair of different vectors u and v () is compared with respect to majorisation, u is chosen as the vector with the first occurrence of a component .
Dimensions, that is, number of nonzero components, of u and v, respectively. In general, and are different.
Supremum of dimensions and .
The vector with the lower
dimension is filled up with zeros to components.
Trace
(sum of components) of u and v, respectively;
(classical)
majorisation, .
Vectors of partial sums of partition vectors u and v, respectively.
(Classical) majorisation relation.
Comparable
pair, where u is being majorised by v and v is majorising. u
In quantum informatics the corresponding transition of entangled
states is possible with certainty by LOCC (local operation and classical communication).
Pair of partition vectors which is comparable with
respect to majorisation.
Pair of partition vectors which is incomparable with respect to
majorisation.
Incomparable pair, where both u and v, respectively, are divided in two subsections of contiguous components, such
that in the first section all partial sums of v are greater or equal to of and in
the second section vice versa.
(For this and the following definitions see also Section 3.2).
Same as but changing subsections of components are repeated k times; in case of one obtains the notation above.
Incomparable pair, where both u and v, respectively, are divided in three subsections of contiguous components, such
that in the first and last (third) section all partial sums of v are greater or equal to of u and in the second section vice versa.
Same as but changing subsections of components are repeated
k times; in case of one obtains the notation above, in case of one
gets the majorisation relation .
