Let $X$ and $Y$ be Polish spaces and $K$ a Markov kernel from $X$ to $Y$. That is, $K$ is a mapping $X \times \mathcal{B}_Y \rightarrow [0,1]$ (where $\mathcal{B}_Y$ is the $\sigma$-algebra of Borel sets on $Y$) s.t.
For every $A \in \mathcal{B}_Y$, the mapping $K^A: X \rightarrow [0,1]$ defined by $K^A(x):=K(x,A)$ is Borel measurable.
For every $x \in X$, the mapping $K_x: \mathcal{B}_Y \rightarrow [0,1]$ defined by $K_x(A):=K(x,A)$ is a probability measure on $Y$.
It seems natural to consider the additional condition on $K$ that $K_x$ depends continuously on $x$ in the sense of the given topology on $X$ and the weak topology on the space $\mathcal{P}(Y)$ of probability measures on $Y$. For example, if $K$ is deterministic (i.e. if for any $x \in X$, $K_x$ is a Dirac measure) this condition means that $K$ defines a continuous mapping from $X$ to $Y$.
What is the standard name for this condition?
