چکیده English

In this paper, generalized binomial edge ideals of corona product of two graphs have been considered. In particular, some explicit formulas for computing the height and the Krull dimension of such ideals in terms of the graphs participating in the corona product have been provided. Moreover, by adding certain special conditions on those graphs, some simpler formulas have been achieved.
