• Resumen

  • In their respective PhD theses, Järvilehto (in [6]) and Tucker (in [9]) studied the relation between the jumping numbers of a curve and their equisingularity class. In this note we present how we can recover the equisingularity class of a tuple of analyticallyirreducible plane curves and the one of its product from its associated jumping walls, and show that in fact, we have enough information with the jumping numbers of each of the branches and those of the product of each pair.
