On Algebraic Numbers and Quadratic Extensions [PDF]
, 2013 . In this thesis some basic properties of algebraic el- ements, integral elements and extensions of rings and elds are investigated. Special focus is given to quadratic extensions.

Rational Expectations Fools' Bubbles
International Economic Review, EarlyView.ABSTRACT We develop a rational, Walrasian model of speculative bubbles inspired by the Kindleberger–Minsky view, which describes bubbles as wave‐like market processes. Touched off by an initial shock, price booms are initially self‐reinforcing but become self‐destructive later when prices surpass fundamental value.

Вероятностный и детерминированный аналоги алгоритма Миллера – Рабина для идеалов колец целых алгебраических элементов конечных расширений поля Q [PDF]
, 2020 In this paper, we obtained the primality criteria for ideals of rings of integer algebraic elements of finite extensions of the field Q, which are analogues of Miller and Euler’s primality criteria for rings of integers.

A Comparative Review of Specification Tests for Diffusion Models
International Statistical Review, EarlyView.Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

On Hilbert's tenth problem over rings of algebraic integers [PDF]
, 2019 Hilberts zehntes Problem fragt, ob ein Algorithmus existiert, der zu gegebenen multivariaten Polynom mit ganzzahligen Koeffizienten entscheiden kann, ob dieses ganzzahlige Nullstellen besitzt.

Journal of Time Series Analysis, EarlyView.ABSTRACT Traditional graph representations are insufficient for modelling real‐world phenomena involving multi‐entity interactions, such as collaborative projects or protein complexes, necessitating the use of hypergraphs. While hypergraphs preserve the intrinsic nature of such complex relationships, existing models often overlook temporal evolution in

Aggregation and the Structure of Value
Noûs, EarlyView.ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

FINITE NEUTROSOPHIC COMPLEX NUMBERS [PDF]
, 2011 In this book for the first time the authors introduce the notion of real neutrosophic complex numbers. Further the new notion of finite complex modulo integers is defined. For every C(Zn) the complex modulo integer iF is such that 2 Fi = n – 1.

Repelled Point Processes With Application to Numerical Integration
Scandinavian Journal of Statistics, EarlyView.ABSTRACT We look at Monte Carlo numerical integration from a stochastic geometry point of view. While crude Monte Carlo estimators relate to linear statistics of a homogeneous Poisson point process (PPP), linear statistics of more regularly spread point processes can yield unbiased estimators with faster‐decaying variance, and thus lower integration ...

Ordered Rings and Fields [PDF]
, 2017 We introduce ordered rings and fields following Artin-Schreier’s approach using positive cones. We show that such orderings coincide with total order relations and give examples of ordered (and non ordered) rings and fields.
