A version of Kalton’s theorem for the space of regular operators
Collectanea Mathematica - Tập 66 - Trang 55-62 - 2014
In this note we extend some recent results in the space of regular operators [appeared in Bu and Wong (Indag Math 23:199–213, 2012), Bu et al. (Collect Math 62:131–137, 2011), and Li et al. (Taiwan J Math 16:207–215, 2012)]. Our main result is the following Banach lattice version of a classical result of Kalton: Let

Well-posedness in weighted Sobolev spaces for elliptic equations of Cordes type
Collectanea Mathematica - Tập 67 - Trang 539-554 - 2015
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

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
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......
Characterizations of space curves containing a planar subcurve
Collectanea Mathematica - Tập 61 - Trang 131-149 - 2010
We introduce and study the space curves of “h-extremal type”, that are curves of degreed and arithmetic genusg whose Rao function agrees, in a suitable interval depending ond andh, with the one of the “h-extremal” curves introduced by NotariSabadini. Our study is motivated by the literature of the last years concerning curves with large cohomology and their relations with the Hilbert scheme. p] Ou......
On the spectra of rings of semialgebraic functions
Collectanea Mathematica - Tập 63 - Trang 299-331 - 2011
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.

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
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......
