Solving Degree Bounds for Iterated Polynomial Systems
For Arithmetization-Oriented ciphers and hash functions Gröbner basis attacks are generally considered as the most competitive attack vector. Unfortunately, the complexity of Gröbner basis algorithms is only understood for special cases, and it is ...

On the first fall degree of summation polynomials
We improve on the first fall degree bound of polynomial systems that arise from a Weil descent along Semaev’s summation polynomials relevant to the solution of the Elliptic Curve Discrete Logarithm Problem via Gröbner basis algorithms.

ABSTRACT We study asymptotic dynamics of Kuramoto oscillators with inertia and frustration using the classical perturbation theory of ordinary differential equation systems. Frustration also known as the phase‐lag poses challenges for the mathematical analysis of asymptotic dynamics due to the breakdown of total phase conservation and the gradient ...

A Zero-Dimensional Gröbner Basis for AES-128
We demonstrate an efficient method for computing a Gröbner basis of a zero-dimensional ideal describing the key-recovery problem from a single plaintext/ciphertext pair for the full AES-128.

An Algebraic Approach to Analyze an MSEIR Epidemic Model
This study introduces a fully algorithmic framework for analyzing the dynamics of an MSEIR (Maternal, Susceptible, Exposed, Infectious, Recovered) epidemic model. Unlike traditional approaches that rely on heuristic, model‐specific Lyapunov functions for global stability or manual algebraic manipulations for finding equilibria, we employ computational ...

A fast algorithm for Gröbner basis conversion and its applications [PDF]
The Gröbner walk method converts a Gröbner basis by partitioning the computation of the basis into several smaller computations following a path in the Gröbner fan of the ideal generated by the system of equations.

Comparing complexities of problems of determining of Grebner’s basis of ideal and solving this ideal
A new method of investigation of ideals in the rings of polynomials was proposed by B. Buchberger in 1965. He proposed to use special basis in such rings named “Gröbner Basis” in the honor of his teacher.

Model category structures on truncated multicomplexes for complex geometry
Abstract To a bicomplex one can associate two natural filtrations, the column and row filtrations, and then two associated spectral sequences. This can be generalized to N$N$‐multicomplexes. We present a family of model category structures on the category of N$N$‐multicomplexes where the weak equivalences are the morphisms inducing a quasi‐isomorphism ...

Polarization and Gorenstein liaison
Abstract A major open question in the theory of Gorenstein liaison is whether or not every arithmetically Cohen–Macaulay subscheme of Pn$\mathbb {P}^n$ can be G‐linked to a complete intersection. Migliore and Nagel showed that if such a scheme is generically Gorenstein (e.g., reduced), then, after re‐embedding so that it is viewed as a subscheme of Pn ...

Identifikasi Basis Gröbner Dalam Ideal Ring Polinomial [PDF]
Dalam suatu ring atau lapangan, dapat didefinisikan suatu polinomial yang koefisien-koefisiennya merupakan elemen dari ring atau lapangan tersebut. [] dan [] merupakan suatu ring yang disebut ring polinomial. Misalkan =〈1,2,…〉⊆[], dengan ≠0 untuk setiap =
