In this paper,the notion of local Sβ-compactness of L-topological spaces is introduced.It is proved that the local Sβ-compactness is an L-good extension,which is inherited by a closed subspace,multiplicative and inv...

In this paper, we consider the following second order three-point boundary value problem u″(t)+a(t)f(u(t))=0,0〈t〈1,u(0)-u(1)=0,u'(0)-u'(1)=u(1/2),where a : (0, 1) → [0, ∞) is symmetric on...
