Extended Skyrme models in even dimensions and higher-dimensional solitons
We propose a higher-dimensional soliton model - an extended Skyrme model - in an even-dimensional spacetime. A hedgehog ansatz is also generalized to higher-dimensional cases and it is found that the soliton generally has the fermion number, i.e., the topological soliton.
