Two Notes on Subshifts
We prove two unrelated results about subshifts. First, we give a condition on the lengths of forbidden words that is sufficient to guarantee that the corresponding subshift is nonempty. The condition implies that, for example, any sequence of binary words of lengths 5, 6, 7, . . . is avoidable. As another application, we derive a result of Durand, Levin and Shen [2, 3] that there are infinite s...
متن کاملTwo notes on the Hippiatrica.
P ELAGONIUS' BOOK on horse medicine,l a main source of Vegetius' Mulomedicina, was composed around the middle of the fourth century. It was later incorporated in the Greek collection of hippiatric texts known as the Hippiatrica. 2 When a Latin manuscript of Pelagonius (originally copied in 1485 on behalf of Politian and bearing his subscriptio 3) was discovered and edited in the early nineteent...
متن کاملTwo Notes on Recursive Functions
Introduction. The theory of regressive isols was introduced by J. C. E. Dekker in [7]. The results that we wish to present in this paper belong to this theory and is a continuation of some of our studies in [1], [3] and [4]. We will assume that the reader is familiar with the terminology and some of the main results of the papers listed as references. We let E denote the collection of all nonne...
متن کاملTwo Notes on Genome Rearrangement
A central problem in genome rearrangement is finding a most parsimonious rearrangement scenario using certain rearrangement operations. An important problem of this type is sorting a signed genome by reversals and translocations (SBRT). Hannenhalli and Pevzner presented a duality theorem for SBRT which leads to a polynomial time algorithm for sorting a multi-chromosomal genome using a minimum n...
متن کاملSome notes on the characterization of two dimensional skew cyclic codes
A natural generalization of two dimensional cyclic code ($T{TDC}$) is two dimensional skew cyclic code. It is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $R_n:=F[x,y;rho,theta]/_l$. In this paper we characterize the left ideals of the ring $R_n$ with two methods and find the generator matrix for two dimensional s...
