Algebraic genericity of frequently universal harmonic functions on trees
N. Biehler, V. Nestoridis, A. Stavrianidi
We show that the set of frequently universal harmonic functions on a tree T contains a vector space except 0 which is dense in the space of harmonic functions on T seen as subset o…

Generic non-extendability and total unboundedness in function spaces
V. Nestoridis, A. G. Siskakis, A. Stavrianidi +1
For a function space $X(\OO)$ satisfying weak assumptions we prove that the generic function in $X(\OO)$ is totally unbounded, hence non-extendable. We provide several examples of…
