Clearly, adjacency tensors and
signless Laplacian tensors are nonnegative.
This proves that permutations at distance p from the identity are exactly the permutations with n - p left-to-right-maxima, which are known to be counted by s(n, n - p), the
signless Stirling number of the first kind (see Flajolet and Sedgewick (2009) for the closed-form formula due to Schlomilch, and sequence OEIS A094638 in Sloane and collaborators (2016) for many occurrences of the corresponding triangular array).
While the bulk of the novel creates a distinction between good and bad interpretation of signs, the last couple of pages open up a wholly different kind of distinction, namely that between a world of signs (and consequently interpretation) and a
signless universe of presence.
Modernity bears witness to the triumph of the machine or mechanism qua typewriter--a
signless cloud--which veils the essence of writing and script through a
signless relation (86).
The recent developments on this topic also involve the problem concerning graphs with maximal or minimal spectral radius,
signless Laplacian spectral radius, and Laplacian spectral radius, of a given class of graphs, respectively.
The Laplacian eigenvalues of G are L(G) = D(G) - A(G) and the
signless Laplacian matrix is Q(G) = D(G) + A(G).
In addition to the natural bases of C[G.sub.n] and [H.sub.n](q), we have the (
signless) Kazhdan-Lusztig bases [KL79] {[C'.sub.W](1)|w [member of] [G.sub.n]}, {[C'.sub.w](q)|w [member of] [G.sub.n]}, defined in terms of certain Kazhdan-Lusztig polynomials {[P.sub.u,[upsilon]](q)|u, [upsilon] [member of] [G.sub.n]} in N[q] by
(v)
Signless graph Laplacian: [absolute value of L] = D + A.
Now a group of businessmen wants the five
signless poles and their footings removed.
The ultimate belongs to the
signless realm, while argumentation belongs to the realm of signs (words and concepts)" (Powers, 1992: 11& 27).
