%0 Journal Article %T Periodic solutions of neutral delay integral equations of advanced type %A Muhammad N. Islam %A Nasrin Sultana %A James Booth %J Electronic Journal of Differential Equations %D 2010 %I Texas State University %X We study the existence of continuous periodic solutions of a neutral delay integral equation of advanced type. In the analysis we employ three fixed point theorems: Banach, Krasnosel'skii, and Krasnosel'skii-Schaefer. Krasnosel'skii-Schaefer fixed point theorem requires an a priori bound on all solutions. We employ a Liapunov type method to obtain such bound. %K Volterra integral equation %K neutral delay integral equation %K periodic solution %K Krasnosel'sii's fixed point theorem %K Schaefer's fixed point theorem %K Liapunov's method %U http://ejde.math.txstate.edu/Volumes/2010/170/abstr.html
