Theory of nonstationary flows of Maxwell fluids in aqueous solutions of polymers
One proves theorems of existence “in the small” for the classical solutions of a periodic initial-boundary-value problem and of the Cauchy problem...

Asymptotic behavior of the spectrum of the Maxwell operator
For the distribution functions of the positive and the negative eigenvalues of the operator in a domain Ω with a smooth boundary, one obtains the...

A theory of pseudo-differential boundary value problems with discontinuous conditions I
The paper deals with mixed boundary value problems and transmission problems for elliptic differential and pseudo-differential operators. These...

Coercive singular perturbations
We consider general boundary value problems with small parameter ɛ in the operator and boundary conditions. Both the perturbed and reduced operators...

Asymptotic behavior of the spectrum of differential equations
This survey is devoted to an exposition of results on the asymptotics of the discrete spectrum of self-adjoint differential operators, mainly partial...

Sistemi ellittici di tipo A.D.N. a coefficienti variabili e condizioni di radiazione
I study an elliptic system, in the sense of Agmon-Douglis-Nirenberg, of partial differential equations with variable coefficients. The matrix...
