On semi weak factorization structures
In this article the notions of semi weak orthogonality and semi weak factorization structure in a category $mathcal X$ are introduced. Then the relationship between semi weak factorization structures and quasi right (left) and weak factorization structures is given. The main result is a characterization of semi weak orthogonality, factorization of morphisms, and semi weak factorization structur...
متن کاملThe Fermat factorization method revisited
We consider the well known Fermat factorization method, we call the Fermat factorization equation the equation solved by it: P(x, y) = (x+ 2R) − y − 4N = 0; where N = p q > 0 is a RSA modulus with primes p and q supposed of equal length. This equation is a bivariate integer polynomial equation and we propose to solve it directly using Coppersmith’s methods for bivariate integer polynomials. As ...
متن کاملMotion Segmentation based on Factorization Method and Discriminant Criterion
A motion segmentation algorithm based on factorization method and discriminant criterion is proposed. This method uses a feature with the most useful similarities for grouping, selected using motion information calculated by factorization method and discriminant criterion. A group is extracted based on discriminant analysis for the selected feature’s similarities. The same procedure is applied ...
متن کاملElliptic Curve Method for Integer Factorization on Parallel Architectures
The elliptic curve method (ECM) for integer factorization is an algorithm that uses the algebraic structure of the set of points of an elliptic curve for factoring integers. The running time of ECM depends on the size of the smallest prime divisor of the number to be factored. One of its main applications is the co-factorization step in the number field sieve algorithm that is used for assessin...
متن کاملRecent Progress on the Factorization Method for Electrical Impedance Tomography
The Factorization Method is a noniterative method to detect the shape and position of conductivity anomalies inside an object. The method was introduced by Kirsch for inverse scattering problems and extended to electrical impedance tomography (EIT) by Brühl and Hanke. Since these pioneering works, substantial progress has been made on the theoretical foundations of the method. The necessary ass...
