Status Report of LPCC Forward Physics Group
We report here about activities of newly formed working group aiming to
define a forward and diffractive physics program at the LHC for the years to
come
The endomorphism semiring of a semilattice
We prove that the endomorphism semiring of a nontrivial semilattice is always subdirectly irreducible and describe its monolith. The endomorphism semiring is congruence simple if and only if the semilattice has both a least and a largest element
The Structure of F-Quasigroups
We solve a problem of Belousov which has been open since 1967: to
characterize the loop isotopes of F-quasigroups. We show that every
F-quasigroup has a Moufang loop isotope which is a central product of its
nucleus and Moufang center. We then use the loop to reveal the structure of the
associated F-quasigroup.Comment: 24 pages. v.2 incorporates minor changes suggested by the referee. To
