Starting from 2009-2010, we run the two seminars in combination. Visit the **main page** to find more information, in particular, programmes of talks for previous years. For the Manchester Geometry Seminar, we meet about 3.45 to collect tea, then take it to the seminar room (FA 1), where there will be biscuits; each lecture begins at 4.15pm.

**February 4: Geometry and Mathematical Physics Seminar. 3pm, FA 2, and 4.15pm, FA 1.***Special Programme on Double and Multiple Structures**Kirill Mackenzie: Integration of Lie algebroids. II*

Kirill will give a recap of last semester and outline the next stages in the proof of the Crainic-Fernandes result.**February 11: Manchester Geometry Seminar. 4.15pm, FA 1.****Dr James Montaldi, (University of Manchester): Morse theory for invariant functions****February 18: Manchester Geometry Seminar. 4.15pm, FA 1.****Dr Jean-Philippe Michel, (Université Claude Bernard Lyon 1): Quantization and conformal geometries of the supercotangent and spinor bundles.****February 25: Manchester Geometry Seminar. 4.15pm, FA 1.****Prof. Victor Buchstaber, (Steklov Mathematical Institute and University of Manchester): Polytopes, Hopf Algebras, and Quasi-Symmetric Functions****March 4: Geometry and Mathematical Physics Seminar. 3pm, FA 2, and 4.15pm, FA 1.***Special Programme on Double and Multiple Structures**Ted Voronov: More on Q-manifolds and Lie algebroids*

Ted will recall the language of Q-manifolds for Lie algebroids and their morphisms with the aim of understanding integration. Then "non-linear Lie algebroids" and a "non-Abelian Poincaré lemma" will be discussed.**March 11: Manchester Geometry Seminar. 4.15pm, FA 1.****Mr Qusay Al-Zamil, (University of Manchester): Witten-Hodge theory for manifolds with boundary and a torus action****March 18: Manchester Geometry Seminar. 4.15pm, FA 1.****Prof. John Rawnsley, (University of Warwick): Symplectic connections****March 25: Geometry and Mathematical Physics Seminar. 3pm, FA 2, and 4.15pm, FA 1.***Special Programme on Double and Multiple Structures**Ted Voronov: More on Q-manifolds and Lie algebroids. II*

Ted wishes to discuss the "non-Abelian Poincaré lemma" and its application to Lie algebroids, which we had no time for at the previous meeting, and he will also try to say more on integration of Lie algebras to Lie groups using Q-manifolds.
