Innovation: Kosten und Gewinnspannen,Partial ordered sets provide a common frame for many combinatorial configurations. Formally, a . (or ., for short) is a set . together with a binary relation < between its elements which is transitive and irreflexive: if . and . then ., but . and . cannot both hold. We write . if . or .. Elements . and . are . if either . or . (or both) hold.

Innovation in BeratungsunternehmenThe use of combinatorial objects, called designs, originates from statistical applications. Let us assume that we wish to compare . varieties of wines. In order to make the testing procedure as fair as possible it is natural to require that:

Peter Sänger,Victor SplittgerberThe general frame for the . in combinatorics is the following: if we want to come up with an upper bound on the size of a set of objects, associate them with elements in a vector space . of relatively low dimension, and show that these elements are linearly independent; hence, we cannot have more objects in our set than the dimension of ..
