Abstract

top
We consider the space D ( X , Y ) of densely continuous forms introduced by Hammer and McCoy and investigated also by Holá . We show some additional properties of D ( X , Y ) and investigate the subspace D * ( X ) of locally bounded real-valued densely continuous forms equipped with the topology of pointwise convergence τ p . The largest part of the paper is devoted to the study of various cardinal functions for ( D * ( X ) , τ p ) , in particular: character, pseudocharacter, weight, density, cellularity, diagonal degree, π -weight, π -character, netweight etc.
