• Fixed point
• weakly lower semicontinuous multimap
• contraction multimap
• weakly closed graph
• measure of noncompactness
• condensing multimap
• countably condensing multimap

We present a Krasnosel'skii-Schaefer-type nonlinear alternative theorem and some fixed point theorems of Krasnosel'skii-Sadowskii (or Daher) type for multimaps. Our results improve or extend in a broad sense recent ones obtained in literature.
