Differentiability of the Solutions of a Semilinear Abstract Cauchy Problems With Respect to Parameters [PDF]
, 2004 The Frechet di®erentiability with respect to a parameter q of the solutions z(t; q) of Cauchy problems of the form d/dt z(t) = A(q)z(t) + F(q; t; z(t)) is analyzed.

Exact Solutions for the Moving Firefighter Problem on Trees
Networks, EarlyView.ABSTRACT The moving firefighter problem (MFP) is a more realistic variant of the classic firefighter problem (FP), where firefighters require time for both travel and defense. Unfortunately, the only known exact solution for the MFP does not scale. In this paper, we establish that the MFP is NP‐complete on trees of maximum degree three and present four

Minimal hermitian matrices with fixed entries outside the diagonal [PDF]
, 2008 We survey some results concerning the problem of finding the complex hermitian matrix or matrices of least supremum norm with variable diagonal. Some qualitative general results are given and more specific descriptions are shown for the 3 x 3 case.

Convergence of Adaptive Finite Element Methods [PDF]
, 2002 Adaptive finite element methods (FEMs) have been widely used in applications for over 20 years now. In practice, they converge starting from coarse grids, although no mathematical theory has been able to prove this assertion.
