• Malikov Comments: 49 pages Subj-class: Quantum Algebra; Algebraic Geometry We define a new modular functor based on Kac-Wakimoto admissible representations and the corresponding D-module on the moduli space of rank 2 vector bundles with parabolic structure. A new fusion functor arises which is related to representation theory of the pair "osp(1|2),sl(2)" in the same way as the fusion functor for the Virasoro algebra is related to representation theory of the pair "sl(2),sl(2)" Full-text: PostScript, PDF, or Other formats.

• The idea in the code that follows is that "functors" wrap polymorphic "functor implementations". Existing functor implementations are in C++ but we should like to be able to design new functor implementations in Python, wrap them up in C++ functors and use them both from C++ and Python. Functor implementations are created by "functor constructor" objects which are registered with a "functor factory". ... p); } }; class functor { cloned_impl_ptr<functor_impl> m_pimpl; public: functor() : m_pimpl(0) {} functor(functor_impl* pimpl) : m_pimpl(pimpl) {} void perform() const { m_pimpl->perform(); } }; class functor_constructor { public: virtual functor create_functor() = 0; virtual functor_impl* create_functor_impl() = 0; }; class functor_factory { private: std::map<std::string, functor_constructor*> m_ctors; public: static functor_factory& instance() { static functor_factory ff; return ff; } void register_functor(std::string const& name , functor_constructor* p_functor_constructor) { m_ctors name = p_functor_constructor; } functor create_functor(std::string const& name) { functor_constructor* p_functor_constructor = m_ctors name ; return p_functor_constructor->create_functor(); } functor_impl* create_functor_impl(std::string const& name) { functor_constructor* p_functor_constructor = m_ctors name ; return p_functor_constructor->create_functor_impl(); } }; struct functor_impl_wrapper : functor_impl { PyObject* m_self; functor_impl_wrapper(PyObject* self) : m_self(self) {} functor_impl_wrapper(PyObject* self , functor_impl const& rhs) : m_self(self), functor_impl(rhs) {} void Attach() const { Py_INCREF(m_self); } void Release() const { Py_DECREF(m_self); } void perform() const { boost::python::call_method(m_self , "perform" , (boost::type<void>*)0); } functor_impl* clone() const { // ??? // how should this be implemented? } }; functor* bind_functor_to_impl(functor_impl* p_impl) { return new functor(p_impl); } struct functor_constructor_wrapper : functor_constructor { PyObject* m_self; functor_constructor_wrapper(PyObject* self) : m_self(self) {} functor_constructor_wrapper(PyObject* self , functor_constructor const& rhs) : m_self(self), functor_constructor(rhs) {} functor_impl* create_functor_impl() { // how should this be implemented? } functor create_functor() { // ??? // how should this be implemented? // first cut was, // return boost::python::call_method(m_self // ,"create_functor" // , (boost::type<functor>*)0)); // but this gives rise to runtime errors due to // attempt to return a dangling reference } }; void invoke_functor_perform(functor const& f) { f. perform(); } void create_functor_and_perform(std::string const& which) { functor f = functor_factory::instance(). ... def(init<functor_impl const&>()) ; class_<functor_constructor , functor_constructor_wrapper , boost::noncopyable>("functor_constructor", init<>()) ; class_<functor>("functor", init<>()). ... def(init<functor const&>()). def("perform", &functor::perform) ; def("bind_functor_to_impl" , &bind_functor_to_impl , return_value_policy<manage_new_object>()) ; class_<functor_factory, boost::noncopyable>("functor_factory", no_init). ...
