Bounded regions correspond to strongly connected digraphs. The... | math |
2,312.06508 | Existing asynchronous distributed optimization algorithms often use diminishing step-sizes that cause slow practical convergence, or use fixed step-sizes that depend on and decrease with an upper bound of the delays. Not only are such delay bounds hard to obtain in advance, but they also tend to be large and rarely att... | math |

2,312.0616 | Let $X$ be a toric Calabi-Yau 3-fold and let $L\subset X$ be an Aganagic-Vafa outer brane. We prove two versions of open WDVV equations for the open Gromov-Witten theory of $(X,L)$. The first version of the open WDVV equation leads to the construction of a semi-simple (formal) Frobenius manifold and the second version ... | math |
2,312.06156 | A marked strongly invertible knot is a triple $(K,h,\delta)$ of a knot $K$ in $S^3$, a strong inversion $h$ of $K$, and a subarc $\delta \subset \operatorname{Fix}(h)\cong S^1$ bounded by $\operatorname{Fix}(h)\cap K\cong S^0$. An invariant Seifert surface for $(K,h,\delta)$ is an $h$-invariant Seifert surface for $K$ ... | math |
2,312.0615 | Conformal field theory (CFT) has become an active area of research beyond its origins in statistical physics and attracted much attention due to its intrinsic mathematical interest, which reveals deep connections with other diverse branches of mathematics. We study a specific subclass of CFTs that involve either uncoup... | math |
2,312.06148 | In this paper, we give matrix formulae for non-orientable surfaces that provide the Laurent expansion for quasi-cluster variables, generalizing the orientable surface matrix formulae by Musiker-Williams. We additionally use our matrix formulas to prove the skein relations for the elements in the quasi-cluster algebra a... | math |
2,312.06143 | This paper investigates the functional calculus of the harmonic oscillator on each Moyal-Groenewold plane, the noncommutative phase space which is a fundamental object in quantum mechanics. Specifically, we show that the harmonic oscillator admits a bounded $\mathrm{H}^\infty(\Sigma_\omega)$ functional calculus for any... | math |
2,312.06139 | Due to uncertainty in demand, sometimes management may delay their planning of shifts later in the horizon when they have more information. We consider a novel dynamic and flexible system for scheduling personnel for work shifts planned at the last minute called 'on-call' shifts. The flexibility in the system allows em... | math |
2,312.06138 | We consider partition functions on the $N\times N$ square lattice with the local Boltzmann weights given by the $R$-matrix of the $U_{t}(\widehat{sl}(n+1|m))$ quantum algebra. We identify boundary states such that the square lattice can be viewed on a conic surface. The partition function $Z_N$ on this lattice computes... | math |
2,312.06132 | We give explicit expressions for MacMahon's generalized sums-of-divisors $q$-series $A_r$ and $C_r$ by relating them to (odd) multiple Eisenstein series. Recently, these sums-of-divisors have been studied in the context of quasimodular forms, vertex algebras, $N=4$ $SU(N)$ Super-Yang-Mills theory, and the study of cong... | math |
2,312.06124 | In this paper, we establish some results concerning the vanishing of specific Ext modules and the finiteness of the Gorenstein dimension of the dual of a certain module, aiming to characterize the freeness of finitely generated modules. | math |
2,312.0612 | In this paper, we shall study the weak solution to the supercritical deformed Hermitian-Yang-Mills equation in the boundary case. | math |
