This survey describes methods for proving tha t systems of rewri te rules terminate . Illust ra t ions of the use of path orderings and other simplification orderings in terminat ion proofs are given. The effect of restrictions, such as l inearity, on the form of rules is considered. In general, though, te rminat ion is an undeeidable p roper ty of rewri te systems. 1. I N T R O D U C T I O N A...
In 2013, Huczynska, Mullen, Panario and Thomson introduced the concept of k-normal elements: an element $$\alpha \in {\mathbb {F}}_{q^n}$$ is over $${\mathbb {F}}_q$$ if greatest common divisor polynomials $$g_{\alpha }(x)= \alpha x^{n-1}+\alpha ^qx^{n-2}+\cdots +\alpha ^{q^{n-2}}x+\alpha ^{q^{n-1}}$$ $$x^n-1$$ in {F}}_{q^n}[x]$$ has degree k, generalizing normal elements (normal usual sense 0-...

the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
