    \begin{talkabstract}
        % Insert talk abstract
        This is the abstract of the talk. It should be concise and informative, 
        summarizing the main point of the presentation. 
        
        The abstract should fit on a single page.

        \begin{theorem}
            This is a sample theorem statement. You need not use theorem environments in your abstract. 
            Please use the theorem environments provided by samsabstract.cls.
        \end{theorem}
        
        References are optional. If you wish to include references 
        they should be hard-coded as in: Smith [1] and Emerson and Grant [2, Theorem~391]. 
        Please do not include unnecessary references or entire bibliographies. 
        One reference is usually sufficient.
