Abstract

Let <em>f</em>: <em>X</em>→ <em>Y</em> be a mapping. <em>f</em> is called a sequence-covering mapping if in case <em>S</em> is a convergent sequence containing its limit point in <em>Y</em> then there is a compact subset <em>K</em> of <em>X</em> such that <em>f</em>( <em>K</em>) = <em>S</em>. It is shown that each quotient and compact mapping of a metric space is sequence-covering. [ABSTRACT FROM AUTHOR]
