Bifurcation sets of extended Higgs potential
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013 One of the most actual problems in modern particle physics is the problem of the baryon charge evidence in the Universe. In the frameworks of supersymmetric models, phase transitions and catastrophe theory it is possible to describe the baryogenesis.

Generalization of Buchberger’s Algorithm with Respect to Several Orderings on Difference Modules
پژوهشهای ریاضی, 2021 Grobner basis with respect to several orderings is a powerful tool to compute multivariate difference dimension polynomials. In this paper, an algorithm for computing a Grobner basis of a difference module over a ground difference field with respect to ...

Groebner Basis Under Composition I [PDF]
, 1998 Composition is the operation of replacing variables in a polynomial with other polynomials. The main question of this paper is:When does composition commute with Groebner basis computation?We prove that this happens iff the composition is ‘compatible ...

Satisfying positivity requirement in the Beyond Complex Langevin approach
EPJ Web of Conferences, 2018 The problem of finding a positive distribution, which corresponds to a given complex density, is studied. By the requirement that the moments of the positive distribution and of the complex density are equal, one can reduce the problem to solving the ...

Block ciphers sensitive to Groebner Basis Attacks [PDF]
, 2005 We construct and analyze Feistel and SPN ciphers that have a sound design strategy against linear and differential attacks but for which the encryption process can be described by very simple polynomial equations. For a block and key size of 128 bits, we

Symbolic Analysis for Boundary Problems: From Rewriting to Parametrized Groebner Bases [PDF]
, 2010 We review our algebraic framework for linear boundary problems (concentrating on ordinary differential equations). Its starting point is an appropriate algebraization of the domain of functions, which we have named integro-differential algebras.

A geometric view of cryptographic equation solving
Journal of Mathematical Cryptology, 2008 This paper considers the geometric properties of the Relinearisation algorithm and of the XL algorithm used in cryptology for equation solving. We give a formal description of each algorithm in terms of projective geometry, making particular use of the ...

SOLVING THE INVERSE KINEMATICAL PROBLEM OF A ROBOT ARM BY USING GROEBNER BASIS [PDF]
, 2021 . The inverse kinematical problem of a robot arm is a problem to find some appropriate joint configurations for a pair of position and direction of a robot hand which is represented by a polynomial equations system.

Mobilizing Documents: Identification, Bureaucracy, and Policing in Transnational Mobility
PoLAR: Political and Legal Anthropology Review, Volume 49, Issue 1, May 2026.ABSTRACT This co‐authored essay builds on a growing anthropological literature that engages critically and creatively with idealized official and popular ideas about documents of/in migration regimes. Documents are often championed as a common and unquestionable good in transnational migration but they are intrinsically tied to inequalities and ...
