A note on the fractional Cauchy problems with nonlocal initial conditions [PDF]

open access: yesApplied Mathematics Letters, 2011
The authors consider the Cauchy problem \[ D^\beta_t u(t)+ Au(t)= f(t,u(t))+ \int^t_0 K(t-s) g(s,u(s))\,ds,\quad t\in [0,T], \] with \(u(0)= H(u)\). Here \(D^\beta_t\) is a fractional time derivative of order \(\beta\in(0, 1)\), \(-A\) generates a compact analytic semigroup \(T(t)\) on a Banach space \(X\), \(u\in C([0,T]; X_\alpha)\) (\(X_\alpha\) the

Semilinear integrodifferential equations with nonlocal initial conditions

open access: yesComputers and Mathematics With Applications, 2004
The paper is concerned with developing existence and uniqueness theorems for the Cauchy problem for semilinear integro-differential equations of convolution type. The sequence of theorems presented extends the existing results and can be applied, as is shown in the final section of the paper, to problems that arise in heat conduction in materials with ...

Controllability of semilinear boundary problems with nonlocal initial conditions

open access: yesJournal of Mathematical Analysis and Applications, 2006
The authors consider a semilinear nonautonomous boundary problem with nonlocal initial conditions. First, they prove the existence of a mild solution of the problem by constructing a contractive map; the solution is given by a variation of constants formula. Ideas of preceeding papers (in press and preprint) are used.
