Uniform decision problems in automatic semigroups
Mark Kambites, Friedrich Otto
We consider various decision problems for automatic semigroups, which involve the provision of an automatic structure as part of the problem instance. With mild restrictions on the…
Automatic Rees matrix semigroups over categories
Mark Kambites
We consider the preservation of the properties of automaticity and prefix-automaticity in Rees matrix semigroups over semigroupoids and small categories. Some of our results are ne…
Word problems recognisable by deterministic blind monoid automata
Mark Kambites
We consider blind, deterministic, finite automata equipped with a register which stores an element of a given monoid, and which is modified by right multiplication by monoid elemen…
Algebraic tools for dealing with the atomic shell model. I. Wavefunctions and integrals for hydrogen--like ions
Andrey Surzhykov, Peter Koval, Stephan Fritzsche
Today, the 'hydrogen atom model' is known to play its role not only in teaching the basic elements of quantum mechanics but also for building up effective theories in atomic and mo…
