Given a homotopy equivalence f between two topological spaces we obtain an explicit formula for a strong deformation retraction of the mapping cylinder of f onto its top.
Filters and open filters are useful utilities to explore structures of domains. In this paper, it is proved that for a continuous distributive semilattice L, OFilt(L) is a distributive lattice iff L i...
Abstract: It is shown that if for a complete metric space $(X,d)$ there is a constant $\epsilon > 0$ such that the intersection $\bigcap_{j=1}^n B_d(x_j,r_j)$ of open balls is nonempty for every finit...
We prove Holder continuity for solutions to the n-dimensional H-System assuming logarithmic higher integrability of the solution.
In the recent paper [2] we proved a Poincar´e inequality on the path space of compound Poisson processes by using transition probabilities and the Markov property. Our purpose is to develop a g...
Let be a smooth bounded domain in RN with N  1. In this paper we study the Hardy-Poincar´e inequalities with weight function singular at the boundary of .In particular we give sufficient condit...
