On the revised Szeged index Original Research Article

We give bounds for the revised Szeged index, and determine the image-vertex unicyclic graphs with the smallest, the second-smallest and the third-smallest revised Szeged indices for image, and the image-vertex unicyclic graphs with the imageth-largest revised Szeged indices for all image up to 3 for image, to 5 for image, to 6 for image, to 7 for image, and to image for image. We also determine the image-vertex unicyclic graphs of cycle length image, image, with the smallest and the largest revised Szeged indices.
