K3 surfaces, cyclotomic polynomials and orthogonal groups
Let X be a complex projective K3 surface and let T-X be its transcendental lattice; the characteristic polynomials of isometries of T-X induced by automorphisms of X are powers of cyclotomic polynomials. Which powers of cyclotomic polynomials occur? The ai ...
Springer Int Publ Ag2024The ellipticity parameterization for an NFW profile: An overlooked angular structure in strong lens modeling
Galaxy-scale gravitational lenses are often modeled with two-component mass profiles where one component represents the stellar mass and the second is a Navarro Frenk White (NFW) profile representing the dark matter. Outside of the spherical case, the NFW ...
Les Ulis Cedex A2023A conformal dispersion relation: correlations from absorption
We introduce the analog of Kramers-Kronig dispersion relations for correlators of four scalar operators in an arbitrary conformal field theory. The correlator is expressed as an integral over its "absorptive part", defined as a double discontinuity, times ...
2020Contract-Based Resource Verification for Higher-Order Functions with Memoization
Viktor Kuncak, Ravichandhran Kandhadai Madhavan, Sumith Kulal
We present a new approach for specifying and verifying resource utilization of higher-order functional programs that use lazy evaluation and memoization. In our approach, users can specify the desired resource bound as templates with numerical holes e.g. a ...
Assoc Computing Machinery2017Scale-invariant alternatives to general relativity. II. Dilaton properties
In the present paper, we revisit gravitational theories which are invariant under TDiffs-transverse (volume-preserving) diffeomorphisms and global scale transformations. It is known that these theories can be rewritten in an equivalent diffeomorphism-invar ...

The development of functional imaging techniques applicable to neuroscience and covering a wide range of spatial and temporal scales has greatly facilitated the exploration of the relationships between cognition, behaviour and electrical brain activity. Fo ...
