چکیده
There is a type of distance-regular graph, said to be $Q$-polynomial. In this paper we investigate generalized $Q$-polynomial property involving graph that not necessarily distance-regular. We give detailed description an example associated with the projective geometry $L_N(q)$.

Integrable Top Equations associated with Projective Geometry over Z2
We give a series of integrable top equations associated with the projective geometry over Z2 as a (2 n − 1)-dimensional generalisation of the 3D Euler top equations. The general solution of the (2 − 1)D top is shown to be given by an integration over a Riemann surface with genus (2 − 1).
متن کاملProjective Geometry with Clifford Algebra*
Projective geometry is formulated in the language of geometric algebra, a unified mathematical language based on Clifford algebra. This closes the gap between algebraic and synthetic approaches to projective geometry and facilitates connections with the rest of mathematics.
متن کاملThe Projective Geometry of a Group
We show that the pair (P(Ω),Gras(Ω)) given by the power set P = P(Ω) and by the “Grassmannian” Gras(Ω) of all subgroups of an arbitrary group Ω behaves very much like a projective space P(W ) and its dual projective space P(W ∗) of a vector space W . More precisely, we generalize several results from the case of the abelian group Ω = (W,+) (cf. [BeKi10a]) to the case of a general group Ω. Most ...
متن کاملDetermination of a Matrix Function in the Form of f(A)=g(q(A)) Where g(x) Is a Transcendental Function and q(x) Is a Polynomial Function of Large Degree Using the Minimal Polynomial
Matrix functions are used in many areas of linear algebra and arise in numerical applications in science and engineering. In this paper, we introduce an effective approach for determining matrix function f(A)=g(q(A)) of a square matrix A, where q is a polynomial function from a degree of m and also function g can be a transcendental function. Computing a matrix function f(A) will be time- consu...
