— We prove that Tian’s invariant on the complex Grassmann manifold Gp,q(C ) is equal to 1/(p + q). The method introduced here uses a Lie group of holomorphic isometries which operates transitively on the considered manifolds and a natural imbedding of ( P(C ) )p in Gp,q(C ). Résumé. — On prouve que l’invariant de Tian sur la grassmannienne Gp,q(C ) est 1/(p+ q). La méthode présentée dans cet ar...
We discuss the definition of conserved quantities in asymptotically locally de Sitter spacetimes. One may define an analogue holographic charges at future and past infinity other Cauchy surfaces $I_t$ as integrals over intersection timelike $C$ surface $I_t$. In general, $Q^t$ defined on depend $C$, but if gravitational flux is absent are independent $C$. On hand, there a net entering or leavin...
This paper deals with Euclidean space codes obtained from two-level group codes of length n over a Generalized Quaternion Group Q,, m23, with 2"' elements, with generators x and y, given by the presentation Q,,,= using a matched labelling of a 4-dimensional signal set with 2" elements with Q,. I. TWO LEVEL GROUP CODES OVER e,. Four dimensional signal sets in conne...
Let c(n, q) be the number of connected labeled graphs with n vertices and q 5 N = ( ) edges. Let x = q/n and k = q n. We determine functions w k 1 , a(x ) and cp(x) such that c (n , q) w k ( z ) e n r p ( x ) e o ( x ) uniformly for all n and q 2 n. If Q > O is fixed, n+= and 4q > ( 1 + ~ ) n log n, this formula simplifies to c(n, q) ( t ) exp(-ne-zq’n). On the other hand, if k = o(n”’), this f...

We refine the techniques of our previous paper [KM1] to prove that the average order of vanishing of L-functions of primitive automorphic forms of weight 2 and prime level q satisfies ∑ f∈S2(q)∗ ords= 1 2 L(f, s) ≤ C|S2(q) ∗| with C = 6.5, for all q large enough. On the Birch and Swinnerton-Dyer conjecture, this implies rank J0(q) ≤ C dim J0(q) for q prime large enough.
We study the number Nγ(n, c, q) of irreducible polynomials of degree n over Fq where the trace γ and the constant term c are given. Under certain conditions on n and q, we obtain bounds on the maximum of Nγ(n, c, q) varying c and γ. We show with concrete examples how our results improve previous known bounds. In addition, we improve upper and lower bounds of any Nγ(n, c, q) when n = a(q − 1) fo...
Density functional theory (DFT) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1H)–one (MPO), as a representative of pyridinone derivatives, at the fullerene (C60) surfaces. Optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (CQ) have been e...
