Title: Sobre la dimensión minimal de las orbitas de una acción de Rn 

Abstract: Considérese una acción diferenciable de Rn sobre una variedad conexa M, no necesariamente compacta, de dimensión m y rango k. Supóngase que M no es un cilindro. Entonces existe una órbita de la acción de dimensión < (m+k)/2.

Como consecuencia se muestra que si existe un elemento no nulo del anillo de clases de Pontrjagin de M de grado 4r>0, entonces existe una órbita de la acción de dimensión menor o igual que m-r-1.

Title: Adjoining roots to ring spectra, algebraic K-theory and chromatic redshift   

Abstract: I will start my talk by providing background on ring spectra and  algebraic K-theory through applications to manifold topology. After this, I will discuss our method for adjoining roots to ring spectra which we exploit to obtain new algebraic K-theory computations and to provide a conceptual approach to some of the known  algebraic K-theory computations. For this, we introduce a new definition of logarithmic THH  and show that root adjunction is logarithmic THH-etale. 

This is a joint work with Christian Ausoni and Tasos Moulinos.
