A Non-Regular Grobner Fan
The Gröbner fan of an ideal I ⊂ k[x1, . . . , xn], defined by Mora and Robbiano, is a complex of polyhedral cones in Rn. The maximal cones of the fan are in bijection with the distinct monomial initial ideals of I as the term order varies. If I is homogeneous the Gröbner fan is complete and is the normal fan of the state polytope of I. In general the Gröbner fan is not complete and therefore no...
متن کاملA non-regular leftist language
A leftist grammar is a rewrite system in which the only kind of production rules allowed are “create left-context” via a −→ ba, and “erase left-context” via ba −→ a. There is a special start symbol, S, which cannot be created or erased, but which can create context. A string w is said to be in L(G) if wS can be transformed through a sequence of rewrite rules to S. To the best of our knowledge, ...
متن کامل2 Comprehensive Grobner System with Inexact Input
Grabner basis is olle of the most important tools ill recent symbolic algebraic computations. Howe\'er, computing a Grobncr basis fo r the given polynomial ideal is lIot easy and it is lIot numcric.. . l1y stable if polynomials have inexact coefficients. I n this paper, we study what we should get for computing a Grabner basis with inexact coefficients alld introduce a naive method to compute a...
متن کاملAssessment of the prevalence of non-alcoholic fatty liver disease in regular and non-regular blood and plasma donors
Abstract Background and Objectives Non-alcoholic liver disease (NAFLD) is a spectrum of diseases, ranging from non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH) which can lead to liver cirrhosis and hepatocellular carcinoma. Nonalchololic fatty liver is the most prevalent hepatic disorder worldwide which can affect up to the one out of four adults. Little is known about...
متن کاملOPTIMAL ANALYSIS OF NON-REGULAR GRAPHS USING THE RESULTS OF REGULAR MODELS VIA AN ITERATIVE METHOD
In this paper an efficient method is developed for the analysis of non-regular graphs which contain regular submodels. A model is called regular if it can be expressed as the product of two or three subgraphs. Efficient decomposition methods are available in the literature for the analysis of some classes of regular models. In the present method, for a non-regular model, first the nodes of the ...
