Spectral Theory of Families of Self-Adjoint Operators

Et moi, ..., si javait su comment en revenir, One service mathematics has rendered the human race. It has put common sense back je ny serais point aile. where it belongs, on the topmost shelf next Jules Verne to the dusty canister labelled discarded n- sense. The series is divergent; therefore we may be Eric T. Bell able to do something with it. O. Hcaviside Mathematics is a tool for thought. A highly necessary tool in a world where both feedback and non- linearities abound. Similarly, all kinds of parts of mathematics seNe as tools for other parts and for other sciences. Applying a simple rewriting rule to the quote on the right above one finds such statements as: One seIVice topology has rendered mathematical physics .. .; One service logic has rendered com- puter science .. .; One service category theory has rendered mathematics .. .. All arguably true. And all statements obtainable this way form part of the raison dj tre of this series.
