Hi, everyone,
Would you please tell me how to shorten the space between the two rows of graphics?

k_] = (-1 + (-1 + \[Alpha]) \[Lambda]s)^2/((1 + \[Alpha] \

In this groups of graphics, there are two graphics in the first row and two in the second row, but the space between the rows are so large, I wonder if there is any solution to solve this problem. Furthermore, how to align the two graphics in the second row? Thank you very much.
