In this note, we consider （2） assuming that f satisfies the following conditions（f₁） and（f₂）. We will de......

Some homotopy classes of the unit spheres are explicitly represented by entire rational maps....

This paper deals with the cyclicity of a kind of degenerate planar polycycles through a saddle-node P0 and two hyperboli......

Let E be a countably generated Hilbert module over a C~*-algebra A and B(E) the set ofall bounded module maps on E. We f......
