Absence of positive solutions of a second-order semilinear parabolic equation with time-periodic coefficients
Sh. G. Bagyrov · Differential Equations · 2014
We consider a parabolic equation with time-periodic measurable bounded coefficients and with a nonlinear source. The equation is studied on the time line and in a domain of x that does not contain the closed unit ball. The definition of a weak solution of the equation is given.
