Well-posedness in weighted Sobolev spaces for elliptic equations of Cordes type
Collectanea Mathematica - Tập 67 - Trang 539-554 - 2015
Loredana Caso, Roberta D’Ambrosio, Maria Transirico
In this paper we prove some weighted $$W^{2,2}$$ -a priori bounds for a class of linear, elliptic, second-order, differential operators of Cordes type in certain weighted Sobolev spaces on unbounded open sets ...... hiện toàn bộ
Comparison theorems for deformation functors via invariant theory
Collectanea Mathematica - Tập 70 Số 1 - Trang 1-32 - 2019
Jan Arthur Christophersen, Jan O. Kleppe
Some results concerning ideal and classical uniform integrability and mean convergence
Collectanea Mathematica - Tập 74 - Trang 1-25 - 2021
Nour Al Hayek, Manuel Ordóñez Cabrera, Andrew Rosalsky, Mehmet Ünver, Andrei Volodin
In this article, the concept of $${\mathcal {J}}$$ -uniform integrability of a sequence of random variables $$\left\{ X_{k}\right\} $$ with respect to ...... hiện toàn bộ
On the Davis-Wielandt shell of an operator and the Davis-Wielandt index of a normed linear space
Collectanea Mathematica - Tập 73 - Trang 521-533 - 2021
Pintu Bhunia, Debmalya Sain, Kallol Paul
We study the Davis-Wielandt shell and the Davis-Wielandt radius of an operator on a normed linear space $$\mathcal {X}$$ . We show that after a suitable modification, the modified Davis-Wielandt radius defines a norm on $$\mathca...... hiện toàn bộ
On the spectra of rings of semialgebraic functions
Collectanea Mathematica - Tập 63 - Trang 299-331 - 2011
José F. Fernando, J. M. Gamboa
In this article we study the most significant algebraic, topological and functorial properties of the Zariski and maximal spectra of rings of semialgebraic and bounded semialgebraic functions on a semialgebraic set.
Weighted estimates for maximal bilinear rough singular integrals via sparse dominations
Collectanea Mathematica - - 2021
Zhidan Wang, Qingying Xue, Xinchen Duan
Let $$x=(x_1,x_2)$$ with $$x_1,x_2 \in \mathbb {R}^n$$ and let $$K(x)={\Omega \big ({x}/{|x|}\big )}{\big |x\big |^{-2n}}$$ ...... hiện toàn bộ
Geometry of rays-positive manifolds
Collectanea Mathematica - - 2011
M. C. Beltrametti, A. L. Knutsen, A. Lanteri, C. Novelli
Let $${\mathcal {M}}$$ be a smooth complex projective variety and let $${\mathcal {L}}$$ be a line bundle on it. Rays-positive manifolds, namely pairs ...... hiện toàn bộ
Integration with respect to Hölder rough paths of order greater than 1/4: an approach via fractional calculus
Collectanea Mathematica - Tập 73 - Trang 13-42 - 2021
Yu Ito
On the basis of fractional calculus, we introduce an integral of controlled paths with respect to Hölder rough paths of order $$\beta \in (1/4,1/3]$$ . Our definition of the integral is given explicitly in terms of Lebesgue integrals for fractional derivatives, without using any arguments from disc...... hiện toàn bộ
Characteristic polyhedra of singularities without completion: part II
Collectanea Mathematica - Tập 72 - Trang 351-392 - 2020
Vincent Cossart, Bernd Schober
Hironaka’s characteristic polyhedron is an important combinatorial object reflecting the local nature of a singularity. We prove that it can be determined without passing to the completion if the local ring is a G-ring and if additionally either it is Henselian, or a certain polynomiality condition (Pol) holds, or a mild condition (*) on the singularity holds. For example, the latter is fulfilled ...... hiện toàn bộ
On the rationality of certain Weierstrass spaces of type (5, g)
Collectanea Mathematica - Tập 62 - Trang 225-238 - 2010
G. Casnati
Let $${\mathfrak{M}_g}$$ be the moduli space of smooth, integral curves of genus g over the complex field $${\mathbb{C}}$$ and denote by ...... hiện toàn bộ
