... signed relative derangements and signed skew derangements. Theorem 2.2. There is a one-to-one correspondence between the set of signed relative derangements on [n] and the set of signed skew derangements ... This goal is achieved by introducing the notion of signed relative derangements, or relative derangements of type B. The concept of derangements...

... structure of a minuscule heap. By the symmetry of the shape of the Dynkin diagram of type ˜ A, to determine the structure of all of 1-intervals is equivalent to determine that of all of v-intervals ... Dynkin diagrams of type ˜ A. From this section on we assume that Γ is a Dynkin diagram of type ˜ A n with the node set N(Γ) := {0, 1, ,n}. (see Figure 1 for the definit...
