On Isometric Embeddings of Graphs
If G is a finite connected graph with vertex set V and edge set E, a standard way of defining a distance da on G is to define dG(x, y) to be the number of edges in a shortest path joining x and y in V. If (M, dM) is an arbitrary metric space, then an embedding X: V-> M is said to be isometric if dG(x, y) = dM(\(x), X(y)) for all x, y e V. In this paper we will lay the foundation for a theory of...
متن کاملSHIFT OPERATOR FOR PERIODICALLY CORRELATED PROCESSES
The existence of shift for periodically correlated processes and its boundedness are investigated. Spectral criteria for these non-stationary processes to have such shifts are obtained.
متن کاملIsometric classification of Sobolev spaces on graphs
Isometric Sobolev spaces on finite graphs are characterized. The characterization implies that the following analogue of the Banach-Stone theorem is valid: if two Sobolev spaces on 3-connected graphs, with the exponent which is not an even integer, are isometric, then the corresponding graphs are isomorphic. As a corollary it is shown that for each finite group G and each p which is not an even...
متن کاملA Shift Operator on L(h 2)
We give definitions and some properties of the shift operator SL(H2) and multiplication operator on L(H ). In addition, we obtain some properties of the commutant of the shift operator SL(H2) and characterize SL(H2)-invariant subspaces.
متن کاملOperator Machines on Directed Graphs
We show that if an infinite-dimensional Banach space X has a symmetric basis then there exists a bounded, linear operator R : X −→ X such that the set A = {x ∈ X : ||Rx|| → ∞} is non-empty and nowhere dense in X. Moreover, if x ∈ X \ A then some subsequence of (Rx)n=1 converges weakly to x. This answers in the negative a recent conjecture of Prǎjiturǎ. The result can be extended to any Banach s...
