Prompt

Create an image of a blackboard with a mathematical expression written in chalk, illustrating the Einstein summation convention. The expression should feature a tensor equation with repeated indices, such as "a_ij * b_jk", with a notation in the corner of the blackboard or a nearby label that reads " summation over j implied". The style should be a realistic depiction of a physics or mathematics lecture setting, with a focus on clearly showing the mathematical notation and the implied summation convention. The color scheme should be muted, with a focus on black, white, and chalkboard gray tones.
