On the studying the spectrum of differential operators’ family whose potentials converge to the Dirac delta function
Background. The paper proposes a new method for studying differential operators with discontinuous coefficients. We study a sequence of differential operators of high even order whose potentials converge to the Dirac delta function. It is assumed that the operator’s potential is a piecewise-summa...
