investigate a model -> proposed by others

solve the model?

spatial variable x means 1D

"f represents the density of the ECM" is not clear. what, on earth, is density of a matrix?




d_{i,j} in the equation next to (3.1) was not defined anywhere. but just mentioned "See [6}

assuming di,j is distanse between xi and xj

instead See [6]


caption of Fig. 1 needs more explanation not only in text

Fig.1I, [7]

__________________________________________________________________________________________________
"solve the model" is not a good expression.


(1) "f represents the density of the ECM" is not clear. what is density of a matrix?
(2) d_{i,j} in the equation next to (3.1) was not defined anywhere. but just mentioned "See [6}
(3) just suggesting like "Fig.1I, [7]" is not good.
(4) caption of Fig. 1 needs more explanation not only in text
(5) author wrote "proposal in [9] + authors proposal (2.6) and (2.7) but [9] does not include those two conditions in it?
(6) more explanation would be necessary for the reason what 1D is sufficient as the spatial variable x.
