What is ( called?

Please provide the rest of your question! "Called" needs a subject. For example, are you asking about a:

• Specific person? (e.g., "Give some information about the artist called...")
• A place? (e.g., "Give some information about the city called...")
• A thing? (e.g., "Give some information about the phenomenon called...")
• A concept? (e.g., "Give some information about the theory called...")

Give me the complete question, and I'll do my best to answer it.
