چکیده
Recently, harmonic functions and frequently universal on a tree T have been studied, taking values separable Fréchet space E over the field C or R. In present paper, we allow to take in vector rather general F. The metric of topological is translation invariant instead can also study more defined by linear combinations with coefficients We don't assume that complete therefore an argument avoiding Baire's theorem.

Visibly pushdown automata on trees: universality and u-universality
An automaton is universal if it accepts every possible input. We study the notion of u-universality, which asserts that the automaton accepts every input starting with u. Universality and u-universality are both EXPTIME-hard for non-deterministic tree automata. We propose efficient antichain-based techniques to address these problems for visibly pushdown automata operating on trees. One of our ...
متن کاملGeneralized Universality
State machine replication reduces distributed to centralized computing. Any sequential service, modeled by a state machine, can be replicated over any number of processes and made highly available to all of them. At the heart of this fundamental reduction lies the so called universal consensus abstraction, key to providing the illusion of single shared service, despite replication. Yet, as univ...
متن کاملOn the Universality of Collins Functions
Collins functions are quark fragmentation functions responsible for some single spin asymmetries in hadronic processes. The functions are defined with gauge links pointing to different directions in different processes. By replacing hadrons with QCD partons we show the universality of Collins functions at parton level. We give arguments to support that the universality also holds at hadron leve...
متن کاملNew Critical Matrix Models and Generalized Universality
We study a class of one-matrix models with an action containing nonpolynomial terms. By tuning the coupling constants in the action to criticality we obtain that the eigenvalue density vanishes as an arbitrary real power at the origin, thus defining a new class of multicritical matrix models. The corresponding microscopic scaling law is given and possible applications to the chiral phase transi...
متن کاملOn Harmonic Functions on Trees
By a tree T we mean a connected graph such that every subgraph obtained from T by removing any of its edges is not connected. In what follows we will only consider trees in which we distinguish a vertex v0 as an origin. As usual we denote by V and E the set of vertices and the set of edges (respectively) of the tree. If v and w are the boundary vertices of an edge, we say that they are neighbou...
