Inverse Sturm-Liouville problems with summable potential
Yuri Ashrafyan, Tigran Harutyunyan
We describe the necessary and sufficient conditions for two sequences {μ_n}^\infty_n=0 and {a_n}^\infty_n=0 to be correspondingly the set of eigenvalues and the set of norming cons…

Gradient of eigenvalues of Dirac operators and its applications
Tigran Harutyunyan, Yuri Ashrafyan
For Dirac operators, which have discrete spectra, the concept of eigenvalues gradient is given and formulae for this gradients are obtained in terms of normalized eigenfunctions. I…

Isospectral Dirac operators
Yuri Ashrafyan, Tigran Harutyunyan
We give the description of self-adjoint regular Dirac operators, on , with the same spectra.
