It is well-known that mixture of hyperons and kaons in nuclear matter
cause softening of matter due to a strong attraction or increased number
of degree of freedom. This softening is one of the most serious problems in
nuclear physics since one has to sustain an observed heavy neutron star with
twice the solar mass.
On the other hand, we have investigated the competition of kaon and
hyperon mixture in nuclei [1]. Then we found that all the kaons put in nuclei
are absorbed in nucleons and converted into hyperons.
In this presentation we discuss the competition between kaons and hyperons in
nucleaer matter in the core of neutron stars.
We also discuss the effect of degenerate electrons and inhomogeneous
structures of matter.
