Let {Q n (α,β) (x)} n=0 ∞ denote the sequence of polynomials orthogonal with respect to the non-discrete Sobolev inner product where λ>0 and d μ α,β(x)=(x?a)(1?x)α?1(1+x)β?1 dx, d ν α,β(x)=(1?x) α (1+x) β dx with a1, α,β>0. Their inner strong asymptotics on (?1,1), a Mehler-Heine type formula as well as some estimates of the Sobolev norms of Q n (α,β) are obtained.

Toric varieties associated with root systems appeared very naturally in the theory of group compactifications. Here they are
considered in a very different context.
We prove the vanishing of higher cohomology groups for certain line bundles on toric varieties associated to GL
n
and G2. This can be considered of general interest and it improves the previously known results for these varieties. We also show
how these results give a simple proof of a converse to Mazur’s inequality for GL
n
and G2 respectively. It is known that the latter imply the nonemptiness of some affine Deligne–Lusztig varieties.

This paper generalises the risk-sensitive cost functional by introducing noise dependent penalties on the state and control variables. The optimal control problems for the full and partial state observation are considered. Using a change of probability measure approach, explicit closed-form solutions are found in both cases. This has resulted in a new risk-sensitive regulator and filter, which are generalisations of the well-known classical results. 相似文献

We obtain several new results for Neumann series of Bessel functions as well as for its various special cases. The generalization of some well-known results for these kind of series, such as the Graf's addition theorem, are also established. 相似文献

C-rich graphitic carbonitride materials (CNx) with a large range of compositions have been prepared thanks to the self-assembly, in different ratios, of melamine (M) and a panel of polycarboxylic acids (A) such as oxalic, tartaric and citric acid. The thermal conversion of the formed adducts (MAy), led to CNx phases, with x ranging from 0.66 to 1.4 (x=1.33 for g-C3N4 for comparison). The properties of these materials were examined by different techniques (XRD, Raman spectroscopy, TEM, TGA, XPS and DRIFT). It appears that the increase in the C content is associated with the disappearance of the long-range order of heptazine units and an increase in the sub-nanometer carbon-rich cluster size within the graphitic g-C3N4 structure. This trend is followed by a significant increase in the interlayer spacing and a lower proportion of N=C−N bonds compared to C=C bonds. The thermal stability under an inert atmosphere of these phases and their UV-Visible absorbance properties were also investigated. 相似文献

Fix a Dynkin graph and let λ be a coweight. When does there exist an element w of the corresponding Weyl group such that w is λ-minuscule and w(λ) is dominant? We answer this question for general Coxeter groups. We express and prove these results using a variant of Mozes’ game of numbers. 相似文献

In this paper a class of linear time-varying control systems is considered. The time variation consists of a scalar time-varying coefficient multiplying the state matrix of an otherwise time-invariant system. Under very weak assumptions of this coefficient, we show that the controllability can be assessed by an algebraic rank condition, Kalman canonical decomposition is possible, and we give a method for designing a linear state-feedback controller and Luenberger observer. 相似文献
