Prompt

Create an image of a 19th-century mathematician standing in front of a large chalkboard filled with complex geometric equations and diagrams, specifically highlighting group theory and symmetry, with a subtle background of the University of Erlangen's architecture; the mathematician is Felix Klein, and he is holding a chalk in his hand, as if he has just finished writing the title "Erlangen Program" on the board, surrounded by papers and books from the Mathematische Annalen journal; convey a sense of innovation and foundational change in geometry and mathematical physics.
