Separating Collections of Points in Euclidean Spaces
Given two disjoint convex sets A and B in Ed, a hyperplane h in Ed separates them if A lies on one of the half spaces defined by h while B lies on the complementary half space. Given a collection F of convex sets in Ed we say F is separated by a set of hyperplanes H if every pair of elements of F i s separated by some hyperplane of H. We deal here with the case that the convex sets are all poin...
متن کاملSeparating invariants
This paper studies separating subsets of an invariant ring or, more generally, of any set consisting of functions. We prove that a subset of a finitely generated algebra always contains a finite separating subset. We also show that a general version of Noether’s degree bound holds for separating invariants, independently of the characteristic. The paper also contains a conceptual investigation ...
متن کاملOn the gap between separating words and separating their reversals
A deterministic finite automaton (DFA) separates two strings w and x if it accepts w and rejects x. The minimum number of states required for a DFA to separate w and x is denoted by sep(w, x). The present paper shows that the difference ∣∣sep(w, x)− sep(w, xR)∣∣ is unbounded for a binary alphabet; here w stands for the mirror image of w. This solves an open problem stated in [Demaine, Eisenstat...
متن کاملBanach module valued separating maps and automatic continuity
For two algebras $A$ and $B$, a linear map $T:A longrightarrow B$ is called separating, if $xcdot y=0$ implies $Txcdot Ty=0$ for all $x,yin A$. The general form and the automatic continuity of separating maps between various Banach algebras have been studied extensively. In this paper, we first extend the notion of separating map for module case and then we give a description of a linear se...
متن کاملPERCUTANEOUS DRAINAGE OF ABDOMINAL ABSCESSES AND FLUID COLLECTIONS
This report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. Aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. Success rate was 90%. Infected collections were successfully drained in 94% and noninfected collections in 72% . Partial success was achieved in two...
