Let f(x) = ∑d s=0 asx s ∈ Z[x] be a polynomial with ad 6≡ 0 mod p. Take z ∈ Fp and let Oz = {fi(z)}i∈Z+ ⊂ Fp be the orbit of z under f , where fi(z) = f(fi−1(z)) and f0(z) = z. For M < |Oz|, we study the diameter of the partial orbit Oz,M = {z, f(z), f2(z), . . . , fM−1(z)} and prove that diam Oz,M & min { M c log logM , Mp , M 1 2p 1 2 } , where ‘diameter’ is naturally defined in Fp and c depe...
The cross sections for inelastic photoproduction of J/ψ and ψ ′ mesons have been measured in ep collisions with the ZEUS detector at HERA, using an integrated luminosity of 468 pb −1 collected in the period 1996–2007. The ψ ′ to J/ψ cross section ratio was measured in the range 0.55 < z < 0.9 and 60 < W < 190 GeV as a function of W , z and p T. Here W denotes the photon-proton centre-of-mass en...
Problems arising in mathematical economics lead to the study of multitime Hamilton-Jacobi equations. Using commutation properties of the semigroups for the standard equation, we propose a generalization of the Hopf formula that gives explicit solutions of these equations. I. Hopf formula. We consider the following Cauchy problem for the HamiltonJacobi equation: ou/ot + H(Du) = 0 mRNx[0,T], u(x,...

— In continuous time, let (Xt)t>0 be a normal martingale (i.e. a process such that both Xt and X 2 t − t are martingales). One says that X has the chaotic representation property if L2 ( σ(X) ) is the (direct) Hilbert sum ⊕ p∈N χp(X), where χp(X) is the space of all p-fold iterated stochastic integrals ∫ 0<t1<...<tp f(t1, . . . , tp) dXt1 . . . dXtp with f square-integrable (χp(X) is called the...

V. D. Milman proved in [14] that the product of two strictly singular operators on L p [0, 1] (1 p < ∞) or on C[0, 1] is compact. In this note we utilize Schreier families S ξ in order to define the class of S ξ-strictly singular operators, and then we refine the technique of Milman to show that certain products of operators from this class are compact, under the assumption that the underlying ...
