Title: Existence and regularity of local solutions 
       to partial neutral functional differential equations 
       with infinite delay

Abstract: 
 In this paper, we establish results concerning, existence,
 uniqueness, global continuation, and regularity of integral
 solutions to some partial neutral functional differential
 equations with infinite delay. These equations find their origin
 in the description of heat flow models, viscoelastic and
 thermoviscoelastic materials, and lossless transmission lines
 models; see for example [15] and [38].
