Mathematical Aspects of Scattering Amplitudes Program Dates: April 15 - May 24, 2024 Location: Harvard CMSA, 20 Garden Street, Cambridge, MA 02138 This program will bring together and foster interaction between theoretical physicists and mathematicians working on various topics connected to recent developments in our understanding of scattering amplitudes in quantum field theory. The field […] 
The CMSA will be hosting a Workshop on Global Categorical Symmetries from April 29–May 3, 2024. Participation in the workshop is by invitation. The workshop will hold three Symmetry Colloquia open to the community on Thursday, May 2, 2024. Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Time: 2:00 - 2:50 pm Speaker: Clay […] |

Symmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Clay Còrdova, University of Chicago Title:  Particle-Soliton Degeneracies from Spontaneously Broken Non-Invertible Symmetry Abstract: We study non-invertible topological symmetry operators in massive quantum field theories in (1+1) dimensions. In phases where this symmetry is spontaneously broken […]

Symmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Theo Johnson-Freyd, Dalhousie University and Perimeter Institute Title: The Universal Target Category Abstract: Hilbert's Nullstellensatz says that the complex numbers C satisfy a universal property among all R-algebras: every not-too-large nonzero commutative R-algebra maps to C. Deligne proved a similar statement […] |
