Extremal Betti Numbers of Some Cohen-Macaulay Binomial Edge Ideals
《Algebra Colloquium》2021年第3期415-430,共16页Carla Mascia Giancarlo Rinaldo 
The first author was supported by the“National Group for Algebraic and Geometric Structures,and Their Applications”(GNSAGA-INdAM).
We provide the regularity and the Cohen-Macaulay type of binomial edge ideals of Cohen-Macaulay cones,and we show the extremal Betti numbers of some classes of Cohen-Macaulay binomial edge ideals:Cohen-Macaulay bipart...

Squarefree Monomial Modules and Extremal Betti Numbers
《Algebra Colloquium》2016年第3期519-530,共12页Marilena Crupi Carmela Ferro 
Let K be a field and let S = K[x1,...,xn] be a polynomial ring over K. Let F = ir=1 Sei be a finitely generated graded free S-module with basis {e1,..., er} in degrees f1,..., fr such that f1≤ f2 ~≤……≤ fr. We exa...

Least-norm and Extremal Ranks of the Least Square Solution to the Quaternion Matrix Equation AXB = C Subject to Two Equations被引量:1
《Algebra Colloquium》2014年第3期449-460,共12页Yubao Bao 
In this paper, we give the expression of the least square solution of the linear quaternion matrix equation AXB = C subject to a consistent system of quaternion matrix equations D1X = F1, XE2 =F2, and derive the maxim...
