Our goal is to assign universal formulas—characteristic classes—to multi-singularities, so that whenever such singularities arise in geometry, their invariants can be obtained by evaluating these formulas in the appropriate context. Inspired by ideas from Geometric Representation Theory, we introduce hbar-deformed universal formulas, describe their structural properties, and develop a method for computing them effectively. As applications, we determine the hierarchy of complex Artin algebras in a wide range and obtain new results toward Mond's conjecture on the Image Milnor Number. Joint work with J. Koncki.
