There is nothing called as List<string,Object> in apex.

Replace your below code

global void execute(Database.BatchableContext BC, List<String, Object> records)


global void execute(Database.BatchableContext BC, List<sObject> records)

Signature for execute method is

public Void execute(Database.BatchableContext jobId, List<sObject> recordList)

So it takes Database.BatchableContext and List<sObject> as parameters, whereas in your code your execute methods takes incorrect values. You can learn more about batch classes at Batchable Interface documentation.
