Variability extremes: statistical validation of the Alfred Wegener Institute Earth System Model (AWI-ESM) [PDF]

Geoscientific Model Development, 2022
Coupled general circulation models are of paramount importance to quantitatively assessing the magnitude of future climate change. Usual methods for validating climate models include the evaluation of mean values and covariances, but less attention is ...

Approximation of the classes $W^{r}_{\beta,\infty}$ by three-harmonic Poisson integrals

Karpatsʹkì Matematičnì Publìkacìï, 2019
In the paper, we solve one extremal problem of the theory of approximation of functional classes by linear methods. Namely, questions are investigated concerning the approximation of classes of differentiable functions by $\lambda$-methods of summation ...

Born-Infeld Corrections to the Entropy Function of Heterotic Black Holes [PDF]

, 2006
We use the black hole entropy function to study the effect of Born-Infeld terms on the entropy of extremal black holes in heterotic string theory in four dimensions.

AdS 2 holography and ModMax

Journal of High Energy Physics, 2023
We present a JT gravity set up in the presence of projected ModMax corrections in two dimensions. Our starting point is the Einstein’s gravity in four dimensions accompanied by the ModMax Lagrangian. The 2D gravity action is obtained following a suitable

Extreme convex set functions with finite carrier: General theory

Discrete Mathematics, 1974
AbstractLet Ω={1,…,n} and P={X:S⊆Ω}. A mapping e : P→R+ is a convex set function if e(⊖)=0 and e(S) + e(T)⩽e(S∩T) + e(S ∪ T) for all S. TϵP. The set of convex set functions for fixed Ω is a convex cone and the paper is dealing with the extreme points of the base 1 = {e: e(Ω)=1} of this cone.

Transformations among large c conformal field theories

, 2005
We show that there is a set of transformations that relates all of the 24 dimensional even self-dual (Niemeier) lattices, and also leads to non-lattice objects that however cannot be interpreted as a basis for the construction of holomorphic conformal ...

Single particle operators and their correlators in free N $$ \mathcal{N} $$ = 4 SYM

Journal of High Energy Physics, 2020
We consider a set of half-BPS operators in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory which are appropriate for describing single-particle states of superstring theory on AdS5 × S 5.

Microstrata

Journal of High Energy Physics, 2023
Microstrata are the non-extremal analogues of superstrata: they are smooth, non-extremal (non-BPS) solitonic solutions to IIB supergravity whose deep-throat limits approximate black holes.

Rotating black holes with equal-magnitude angular momenta in d=5 Einstein-Gauss-Bonnet theory

, 2010
We construct rotating black hole solutions in Einstein-Gauss-Bonnet theory in five spacetime dimensions. These black holes are asymptotically flat, and possess a regular horizon of spherical topology and two equal-magnitude angular momenta associated ...

Positional Games [PDF]

, 2014
Positional games are a branch of combinatorics, researching a variety of two-player games, ranging from popular recreational games such as Tic-Tac-Toe and Hex, to purely abstract games played on graphs and hypergraphs.
