Under the framework of sublinear expectation,we introduce a new type of G-Gaussian random fields,which contains a type of spatial white noise as a special case.Based on this result,we also introduce a spatial-temporal G-white noise.Different from the case
We consider the deformations of complex orbifolds with the underlying smooth structures being fixed.As a corollary,we can prove that the deformations of a Calabi-Yau orbifold is unobstructed by using standard arguments.Then we consider the period map for
The rainfall over the Yangtze River Valley(YRV)in June 2020 broke the record since 1979.Here we show that all three oceans of the Pacific,Indian and Atlantic Oceans contribute to the YRV rainfall in June 2020,but the Atlantic plays a dominant role.The sea
Regionality,comprehensiveness,and complexity are regarded as the basic characteristics of geography.The exploration of their core connotations is an essential way to achieve breakthroughs in geography in the new era.This paper focuses on the important met
In this paper,effect of geometric parameters and grazing incidence on excitation of magnetic polaritons(MPs)in a 1D multi-groove grating with different groove depths made of silver was studied.Numerical results reveal that when the distance between groove
Concrete is the most widely used composite material in civil engineering.Microbial induced calcium carbonate precipitation(MICP)is a green and environmental friendly technology,which has received extensive attention in repair of concrete cracks.This paper
Tensor decomposition and tensor networks (TNs) are factorizations of high order tensors into a network of low-order tensors,which have been studied in quantum physics,chemistry and applied mathematics.In recent years,TNs have been increasingly investigate
In the standard model of particle physics,the baryon is formed by three quarks.Unlike the well-known proton and neutron that are composed of three light quarks,the doubly charmed baryon consists of two heavy charm quarks and a light quark.Therefore,it is
In this paper,we give a new genus-4 topological recursion relation for Gromov-Witten invariants of compact symplectic manifolds via Pixton\'s relations on the moduli space of curves.As an application,we prove that Pixton\'s relations imply a known top
