abstract = {<p style="text-align: justify;">We consider eigenvalue perturbation bounds for Hermitian matrices, which
are associated with problems arising in various computational science and engineering
applications. New bounds are discussed that are sharper than some existing ones,
including the well-known Weyl bound. Two numerical examples are investigated, to
illustrate our theoretical presentation.</p>},
