In this paper we continue the study of interconnections between separately continuous function which was started by V. K. Maslyuchenko. A pair (g, h) of functions on a topological space is called a pair of Hahn if g ≤ h, g is an upper semicontinuou

We prove that a function which dened on the product of two metric Baire spaces is the oscillation of some separately locally Lipschitz function if and only if it is an upper semicontinuous non-negative function which has a crosswise nowhere dense clo

We investigate the following problem: which dense subspaces$L$ of the Banach space $C(Y)$ of continuous functions on acompact $Y$ and topological spaces $X$ have such property, thatfor every separately or jointly continuous functions $f: X\times Y\ri

We continue to study cluster sets of a function defined on an open subset of a topological space. In our previous papers we characterized the cluster multifunction of any function and of a continuous function. The next aim was to study cluster sets o

We give a norm estimate in the Kalton–Rosenthal representation theorem for operators on L 1 . One of the main results asserts that, if T = T P E + T N is the representation of an operator T ∈ L ( L 1 ) , where T P E is a pseudo embedding and T N

In this paper we continue our research of functions on the boundary of their domain and obtain some results on cluster sets of functions between topological spaces. In particular, we prove that for a metrizable topological space $X$, a dense subspace

We prove that a compact-valued multifunction F: X × Y → Z, where X is a Baire space and Y, Z are separable metrizable spaces, is quasi-continuous if and only if F is horizontally quasi-continuous and there exists an residual subset M of X such tha
