In the study of the constant in Ahlfors' second fundamental theorem involving a set Eq consisting of q points,branch values of covering surfaces outside Eq brin
The partial inverse problem for differential pencils on a star-shaped graph is studied from mixed spectral data.More precisely,we show that if the potentials on
Organic azides have shown versatile reactivity to induce various organic transformations for the synthesis of nitrogencontaining organic molecules such as 1,3-d
We study a new set of duality relations between weighted,combinatoric invariants of a graph G.The dualities arise from a non-linear transform B,acting on the we
