Švitra, Donatas; Sirvydaitė, Ingrida On the location of some quasipolynomial roots. (Russian. English summary) Zbl 1207.34102 Liet. Mat. Rink. 44, Spec. Iss., 174-179 (2004). Summary: The location of quasipolynomial roots in a complex plane that appear while we inverstigate differential equations of the locator and the combustion process in the rocket engine is analysed. The same research is carried out for a differential equation with delay of neutral type appearing in mathematical ecology.
