Mantošanas regulas piemērošana, vedot mantojuma lietu pie Latvijas notāra un ar to saistītie problēmjautājumi.

2020

Bakalaura darbā ir pētīta Eiropas Parlamenta un Padomes Regulas (ES) Nr. 650/2012 (2012. gada 4. jūlijs) par jurisdikciju, piemērojamiem tiesību aktiem, nolēmumu atzīšanu un izpildi un publisku aktu akceptēšanu un izpildi mantošanas lietās un par Eiropas mantošanas apliecības izveidi jeb Mantošanas regulas piemērošanas problemātika gadījumos, kad mantojuma lieta tiek vesta pie Latvijas notāra. Darba mērķis ir analizēt Mantošanas regulas būtiskākos jēdzienus, Mantošanas regulas atbilstību tās sākotnējiem mērķiem, kā arī izpētīt ar kādiem izaicinājumiem ir jāsaskaras Mantošanas regulas piemērotājiem Latvijā un sniegt atbilstošus risinājumus, lai atvieglotu Mantošanas regulas piemērošanu.

Jurisdikcijas noteikšana pārrobežu mantojuma lietās

2022

Autore maģistra darbā “Jurisdikcijas noteikšana pārrobežu mantojuma lietās” pievērš uzmanību aktualitātēm un problēmjautājumiem, kas saistīti ar Eiropas Savienības Mantošanas regulas izpratni un piemērošanu. Dalībvalstis joprojām sastopas ar jurisdikcijas noteikšanas grūtībām pārrobežu mantojuma lietās, par ko liecina Eiropas Savienības Tiesā iesniegto prejudiciālo jautājumu skaits. Tādēļ galvenais darba mērķis ir rast skaidru pieeju jurisdikcijas noteikšanai, gan notāram vedot pārrobežu mantojuma lietu, gan tiesai risinot strīdu. Ņemot vērā nozīmīgās domstarpības par jurisdikcijas noteikšanu pārrobežu mantojuma lietā, autore pievēršas šim Latvijas tiesību doktrīnā maz pētītajam problēmjaut…

Gaps in International Biodiversity Law and Possible Ways Forward

2021

Building on the report on gaps in international environmental law prepared in 2018 by the UN Secretary-General, this chapter focuses on the existing gaps in international biodiversity law and explores possible ways forward to a more effective and integrated legal regime. The analysis indicates the existence of structural, regulatory and implementation gaps that seriously undermine the efficiency of the regime. The chapter explores the possibility of building a more integrated international legal regime for biodiversity protection by analysing three possible avenues: greater integration between existing conventions, the conclusion of new conventions (such as the impending agreement on marine…

Short time existence of the classical solution to the fractional mean curvature flow

2019

Abstract We establish short-time existence of the smooth solution to the fractional mean curvature flow when the initial set is bounded and C 1 , 1 -regular. We provide the same result also for the volume preserving fractional mean curvature flow.

Inverse problems for elliptic equations with power type nonlinearities

2021

We introduce a method for solving Calder\'on type inverse problems for semilinear equations with power type nonlinearities. The method is based on higher order linearizations, and it allows one to solve inverse problems for certain nonlinear equations in cases where the solution for a corresponding linear equation is not known. Assuming the knowledge of a nonlinear Dirichlet-to-Neumann map, we determine both a potential and a conformal manifold simultaneously in dimension $2$, and a potential on transversally anisotropic manifolds in dimensions $n \geq 3$. In the Euclidean case, we show that one can solve the Calder\'on problem for certain semilinear equations in a surprisingly simple way w…

RECOVERY OF THE SOUND SPEED FOR THE ACOUSTIC WAVE EQUATION FROM PHASELESS MEASUREMENTS

2018

We recover the higher order terms for the acoustic wave equation from measurements of the modulus of the solution. The recovery of these coefficients is reduced to a question of stability for inverting a Hamiltonian flow transform, not the geodesic X-ray transform encountered in other inverse boundary problems like the determination of conformal factors. We obtain new stability results for the Hamiltonian flow transform, which allow to recover the higher order terms.

Approximation by mappings with singular Hessian minors

2018

Let $\Omega\subset\mathbb R^n$ be a Lipschitz domain. Given $1\leq p<k\leq n$ and any $u\in W^{2,p}(\Omega)$ belonging to the little H\"older class $c^{1,\alpha}$, we construct a sequence $u_j$ in the same space with $\operatorname{rank}D^2u_j<k$ almost everywhere such that $u_j\to u$ in $C^{1,\alpha}$ and weakly in $W^{2,p}$. This result is in strong contrast with known regularity behavior of functions in $W^{2,p}$, $p\geq k$, satisfying the same rank inequality.

Gradient estimates for heat kernels and harmonic functions

2020

Let $(X,d,\mu)$ be a doubling metric measure space endowed with a Dirichlet form $\E$ deriving from a "carr\'e du champ". Assume that $(X,d,\mu,\E)$ supports a scale-invariant $L^2$-Poincar\'e inequality. In this article, we study the following properties of harmonic functions, heat kernels and Riesz transforms for $p\in (2,\infty]$: (i) $(G_p)$: $L^p$-estimate for the gradient of the associated heat semigroup; (ii) $(RH_p)$: $L^p$-reverse H\"older inequality for the gradients of harmonic functions; (iii) $(R_p)$: $L^p$-boundedness of the Riesz transform ($p<\infty$); (iv) $(GBE)$: a generalised Bakry-\'Emery condition. We show that, for $p\in (2,\infty)$, (i), (ii) (iii) are equivalent, wh…

Fixed angle inverse scattering in the presence of a Riemannian metric

2020

We consider a fixed angle inverse scattering problem in the presence of a known Riemannian metric. First, assuming a no caustics condition, we study the direct problem by utilizing the progressing wave expansion. Under a symmetry assumption on the metric, we obtain uniqueness and stability results in the inverse scattering problem for a potential with data generated by two incident waves from opposite directions. Further, similar results are given using one measurement provided the potential also satisfies a symmetry assumption. This work extends the results of [23,24] from the Euclidean case to certain Riemannian metrics.

Reliability of rainfall kinetic power-intensity relationships

2017

The rainfall erosivity plays a fundamental role in water soil erosion processes and it can be expressed by its kinetic power. At first in this paper the raindrop size distributions measured, in the period June 2006- March 2014, by an optical disdrometer installed at the Department of Agricultural and Forestry Sciences of University of Palermo are aggregated into rainfall intensity classes, having different ranges, and the measured kinetic power values are determined. Measured kinetic power values are initially used for testing the applicability of the kinetic power-rainfall intensity relationships proposed by Wischmeier and Smith (1978), used in Universal Soil Loss Equation (USLE), Brown an…
