This　work　is　to　analyze　a　spectral　Jacobi-collocation　approximation　for　Volterra　integral　equations　with　singular　kernel　φ(t,　s)　=　(t　-　s)　-μ.　In　an　earlier　work　of　Y.　Chen　and　T.　Tang　[J.　Comput.　Appl.　Math.,　2009,　233:　938-950],　the　error　analysis　for　this　approach　is　carried　out　for　0　<μ<1/2　under　the　assumption　that　the　underlying　solution　is　smooth.　It　is　noted　that　there　is　a　technical　problem　to　extend　the　result　to　the　case　of　Abel-type,　i.　e.,　μ　=　1/2.　In　this　work,　we　will　not　only　extend　the　convergence　analysis　by　Chen　and　Tang　to　the　Abel-type　but　also　establish　the　error　estimates　under　a　more　general　regularity　assumption　on　the　exact　solution.　©　2012　Higher　Education　Press　and　Springer-Verlag　Berlin　Heidelberg.
