We deal with a Carleson measure type problem for the tent spaces ATpq(α) in unit disc of complex plane. They consist analytic functions Tpq(α) introduced by Coifman, Meyer and Stein. Well known like Bergman arise as special case this family. Let s,t,p,q∈(0,∞) α>0. find necessary sufficient conditions on positive Borel μ order to exist constant C such that∫T(∫Γ(ξ)|f(z)|tdμ(z))s/t|dξ|≤C‖f‖Tpq(α)s...
The μ-basis of a rational ruled surface P(s, t) = P0(s)+tP1(s) is defined in Chen et al. (Comput. Aided Geom. Design 18 (2001) 61) to consist of two polynomials p(x, y, z, s) and q(x, y, z, s) that are linear in x, y, z. It is shown there that the resultant of p and q with respect to s gives the implicit equation of the rational ruled surface; however, the parametric equation P(s, t) of the rat...

From Quantum to Elliptic Algebras on Leave of Absence from Laboratoire De Physique Théorique Enslapp
It is shown that the elliptic algebra Aq,p(sl(2)c) at the critical level c = −2 has a multidimensional center containing some trace-like operators t(z). A family of Poisson structures indexed by a non-negative integer and containing the q-deformed Virasoro algebra is constructed on this center. We show also that t(z) close an exchange algebra when p m = q c+2 for m ∈ Z, they commute when in add...
background and aims: chronic obstructive pulmonary disease (copd) is a kind of pulmonary diseases characterized by chronic obstruction of lung that is in the form of a diffuse narrowing of airways resulting in air flow resistance. alpha-1 antitrypsin (aat) deficiency is genetically relatively common risk factor in patients with copd throughout the world and the exact cause of its prevalence is ...
A filter F on a group G is a T -filter if there is a Hausdorff group topology τ on G such that F τ −→ 0. This notion can be specialized for sequences, in which case we say that {an} is a T -sequence. In this paper, T -filters and T -sequences are studied. We characterize T -filters in non-abelian groups, show that certain filters can be interpreted as topological extensions of the notion of ker...
OBJECTIVE Most studies have shown contradictory results regarding predictive factors of osteoporosis in inflammatory bowel disease (IBD). Since in these studies either T- or Z-scores has been used, our aim was to compare T- and Z-score in identifying risk factors of osteoporosis in IBD patients. MATERIALS AND METHODS Bone density was measured by dual X-ray absorptiometry (DXA) at L2-L4 of the...

or, in vector notation, Cs = Xsβ1 + Zsβ s 2 + Vs, where Cs = [Cs1, . . . , CsT ] ′ is T × 1, Xs = [xs1, . . . , xsT ] ′ is T ×k1, Zs = [zs1, . . . , zsT ]′ is T ×k2, and Vs = [vs1, . . . , vsT ]′ is T ×1. Also, let xsth be the h th element of xst so that x ′ st = [xst1, . . . , xstk1 ], and define zsth similarly. Define v̈st = vst − z′ st(Z ′ sZs)Z ′ sVs, ẍst = xst − z′ st(Z ′ sZs)Z ′ sXs, V̈s = ...
