We introduce and start the study of a bialgebra of graphs, which we call the 4-bialgebra, and of the dual bialgebra of 4-invariants. The 4-bialgebra is similar to the ring of graphs introduced by W. T. Tutte in 1946, but its structure is more complicated. The roots of the definition are in low dimen

Previously we obtained a PicardแBrauer five term exact sequence for a symmetric monoidal functor between closed categories. Here we construct the corresponding sequence using the closed category of H-modules for a cocommutative Hopf algebra H.
We study the stability of a singular point for planar discontinuous differential equations with a line of discontinuities. This is done, for the most generic cases, by computing some kind of Lyapunov constants. Our computations are based on the ลฝ . so called R, , p, q -generalized polar coordinates,
