Revista Matematica Complutense, 2019 In this paper we investigate the dynamical properties of weighted translation operators acting on the Schwartz space $$\mathcal {S}(\mathbb {R})$$S(R) of rapidly decreasing functions, i.e., operators of the form $${T_w}:{\mathcal {S}(\mathbb {R ...

Absence of Non-Trivial Fuzzy Inner Product Spaces and the Cauchy–Schwartz Inequality
Mathematics, 2020 First, we show that the non-trivial fuzzy inner product space under the linearity condition does not exist, which means a fuzzy inner product space with linearity produces only a crisp real number for each pair of vectors. If the positive-definiteness is

Using the Circular Model to Analyse Political Values: The Case of the Pirate Parties
Polish Political Science Yearbook, 2023 Political parties that operate in the public space are classified, inter alia, according to the criterion of their ideological convergence (Mair, 2010; Gallagher, Laver, Mair, 2011).

Forecasting of commodities prices using a multi-factor PDE model and Kalman filtering
IET Cyber-Physical Systems, 2018 This study proposes a method for forecasting commodities prices using Schwartz partial differential equation (PDE) and Kalman filtering. The method is applicable to both the single-factor and the multi-factor Schwartz PDE.

The boundedness of a class of semiclassical Fourier integral operators on Sobolev space $H^{s}$
Математичні Студії, 2021 We introduce the relevant background information that will be used throughout the paper. Following that, we will go over some fundamental concepts from the theory of a particular class of semiclassical Fourier integral operators (symbols and phase ...

Spectral synthesis for the differentiation operator in the Schwartz space [PDF]
, 2016 We consider the spectral synthesis problem for the differentiation operator on the space of infinitely differentiable functions on a finite or infinite interval of the real line and the dual problem of local description of closed submodules in a special ...
