The Membership Problem for 〈 a , b : bab 2 = ab 〉

Throughout, P is the semigroup presentation 〈a, b: bab = ab〉 for the semigroup S1. Lallement and Rosaz, [5], have shown that the semigroups Sk having presentations 〈a, b: b(ab)b = ab〉 are residually finite. They also find normal forms for elements of Sk . Specialized to k = 1, every element of S1 is either a power of a or else it can be represented uniquely by a word in one of the forms aba or ...

Comparison of A-block polydispersity effects on BAB triblock and AB diblock copolymer melts.

Recent experiments on triblock copolymer melts suggest that polydispersity effects are dramatically enhanced when polydisperse blocks are constrained by both ends to the internal interfaces of an ordered morphology. To quantify the relevance of architecture, we compare BAB triblock and AB diblock copolymer melts with polydisperse A blocks and monodisperse B blocks, using self-consistent field t...
