Resonant neumann equations with indefinite linear part

2015

We consider aseminonlinear Neumann problem driven by the $p$-Laplacian plus an indefinite and unbounded potential. The reaction of the problem is resonant at $\pm \infty$ with respect to the higher parts of the spectrum. Using critical point theory, truncation and perturbation techniques, Morse theory and the reduction method, we prove two multiplicity theorems. One produces three nontrivial smooth solutions and the second four nontrivial smooth solutions.

Weak chord-arc curves and double-dome quasisymmetric spheres

2014

Let $\Omega$ be a planar Jordan domain and $\alpha>0$. We consider double-dome-like surfaces $\Sigma(\Omega,t^{\alpha})$ over $\overline{\Omega}$ where the height of the surface over any point $x\in\overline{\Omega}$ equals $\text{dist}(x,\partial\Omega)^{\alpha}$. We identify the necessary and sufficient conditions in terms of $\Omega$ and $\alpha$ so that these surfaces are quasisymmetric to $\mathbb{S}^2$ and we show that $\Sigma(\Omega,t^{\alpha})$ is quasisymmetric to the unit sphere $\mathbb{S}^2$ if and only if it is linearly locally connected and Ahlfors $2$-regular.

Relatively weakly open convex combinations of slices

2018

We show that c 0 c_0 and, in fact, C ( K ) C(K) for any scattered compact Hausdorff space K K have the property that finite convex combinations of slices of the unit ball are relatively weakly open.

Strongly extreme points and approximation properties

2017

We show that if $x$ is a strongly extreme point of a bounded closed convex subset of a Banach space and the identity has a geometrically and topologically good enough local approximation at $x$, then $x$ is already a denting point. It turns out that such an approximation of the identity exists at any strongly extreme point of the unit ball of a Banach space with the unconditional compact approximation property. We also prove that every Banach space with a Schauder basis can be equivalently renormed to satisfy the sufficient conditions mentioned. In contrast to the above results we also construct a non-symmetric norm on $c_0$ for which all points on the unit sphere are strongly extreme, but …

On holomorphic functions attaining their norms

2004

Abstract We show that on a complex Banach space X , the functions uniformly continuous on the closed unit ball and holomorphic on the open unit ball that attain their norms are dense provided that X has the Radon–Nikodym property. We also show that the same result holds for Banach spaces having a strengthened version of the approximation property but considering just functions which are also weakly uniformly continuous on the unit ball. We prove that there exists a polynomial such that for any fixed positive integer k , it cannot be approximated by norm attaining polynomials with degree less than k . For X=d ∗ (ω,1) , a predual of a Lorentz sequence space, we prove that the product of two p…

Terminoloģijas pārnese ar lietu tiesībām saistītu dokumentu tulkojumos no angļu valodas latviešu valodā

2017

Lietu tiesības ir būtisks koncepts, kas apzīmē dzīves telpu, valdījumu un iesaistīto pušu tiesiskos pienākumus un saistības. Pieaugošā globalizācijas ietekme pieprasa tādu terminoloģisko ekvivalentu nepieciešamību, kas nodrošinātu to pašu ietekmi un tiesiskās sekas gan oriģinālvalodā, gan mērķa valodā. Šī pētījuma mērķis ir apskatīt, vai juridiskās ekvivalences princips ir ievērots ar lietu tiesībām saistītas terminoloģijas pārnesē no angļu valodas latviešu valodā. Šī analīze izmanto kvalitatīvo pētījuma metodi, izvērtējot ar lietu tiesībām saistītu terminu nozīmi, funkciju un lietojumu. Rezultāti norāda uz to, ka izvēlētie termini seko juridiskās ekvivalences principam, uzsverot kultūras u…

Perceived problems with collateral: The value of informal networking

2020

Abstract Many businesses in emerging economies are financially constrained due to their limited use of formal loans. Recent evidence suggests that negative perceptions discourage entrepreneurs from applying for loans. One of the main issues entrepreneurs mention is unattainable collateral requirements. In this paper, we contribute to this line of research by investigating the effect of networking with fellow entrepreneurs on perceived collateral problems. Drawing on quantitative and qualitative data originating from female entrepreneurs in Tanzania, we find that through networking, entrepreneurs are exposed to stories of their peers’ experiences with loans which influence their perceptions …

Patterns of Transnational Urban Drift to Latvia

2021

This chapter extends the previous knowledge on the effects of migrants’ transnational lifestyle by studying residential patterns and life preferences of Latvian return migrants and arriving foreigners. We aim to explore the geographies and narratives from interviews with migrants who had shifted to more dynamic and prosperous urban/suburban locations. The contribution sends forward the interplay between immigration and return migration experiences by questioning: (1) What are the migratory flows’ geographical contexts? (2) How do they overlap and illuminate the process of ‘urban drift’? (3) How do the ‘urban drifters’ value their current life preferences and migratory experiences? Using sec…

The Role of Public Entity in Coopetiotion and Convergence

2007

We investigate upon the strategic impact of the public entity to catalyze coalition formation among competitors around an essential facility. The public entity is usually represented as if moved by mere political scopes. However, the presence of a publicly-owned asset or infrastructure, which can be termed an essential facility, gives leeway to shed the opportunity to satisfy potentially new and different type of demand or consumer cluster needs. The increase in value stemming from a renewal in the utilization of the facility might loosen up political restraints against the involvement in the management of the facility of a multiplicity of actors. This allows us to add a new dimension to th…
