For four decades, a quiet boundary in pure mathematics kept a powerful theorem locked inside the safe world of finite quantities. Now a new result known as Sebestyen’s theorem has pushed that boundary ...

Let {fm}m ≥ 1 be a sequence of holomorphic functions defined on a bounded domain D ⊂ ℂn or a sequence of rational functions (1 ≤ deg rm ≤ m) defined on ℂn. We are interested in finding sufficient ...

Existence and boundedness theorems are given for solutions of abstract nonlinear Volterra equations of the type $\mathrm{u}\left(\mathrm{t}\right)+{\int }_{0 ...
