Hecke Operators on Vector-Valued Modular Forms [PDF]

open access: yes, 2019
We study Hecke operators on vector-valued modular forms for the Weil representation $\rho_L$ of a lattice $L$. We first construct Hecke operators $\mathcal{T}_r$ that map vector-valued modular forms of type $\rho_L$ into vector-valued modular forms of ...

On isomorphisms between Siegel modular threefolds

open access: yes, 2015
The Satake compactification of the moduli space of principally polarized abelian surfaces with a level two structure has a degree 8 endomorphism. The aim of this paper is to show that this result can be extended to other modular threefolds.

Modular Construction to Support Airport Sustainability at US Airports

open access: yesFuture Transportation
This paper explores how modular construction can enhance airport sustainability, highlighting example applications at US airports. Whereas traditional construction builds sequentially on-site, modular construction (also known as prefabricated, off-site ...

Numerical Study of Structural Performance and Wind Flow Dynamic Behavior for PPVC Steel Modular Construction (MSC) under Various Extreme Wind Loads

open access: yesBuildings, 2022
PPVC modular construction building has become one of the most recent construction technologies in the civil engineering sector and has piqued researchers’ interest. Few published studies consider the overall structural response to extreme wind load. As a

Modularity, Quaternion-Kahler spaces and Mirror Symmetry

open access: yes, 2013
We provide an explicit twistorial construction of quaternion-Kahler manifolds obtained by deformation of c-map spaces and carrying an isometric action of the modular group SL(2,Z).

Using Modular Construction Terms

open access: yesWays to Improve Construction Efficiency, 2022
With the growing number of international construction projects, the development of the international building materials market and the European integration of Ukraine, there is a growing need to harmonize common terminology in this area. When translating, new borrowed terms still have weak family ties in the new language, which means there is a high ...

Contractor Perceptions of Off-Site Modular Construction in Kuwait: An Investigation of Current Practices

open access: yesEngineering Proceedings
Kuwait faces a pressing challenge in expanding its existing buildings to meet growing demands. The rising popularity of modular construction systems, with their off-site construction approach, offers promising solutions. In this research, we explored the

Constructing modular separating invariants

open access: yesJournal of Algebra, 2009
Consider a finite dimensional representation \(V\) of a group \(G\) over a field \(F\). The induced action on the dual \(V^*\) extends to an action by algebra automorphisms on the symmetric algebra \(F[V]:=S(V^*)\). The elements of \(F[V]\) represent polynomial functions on \(V\). An invariant polynomial \(f\in F[V]^G\) is constant on \(G\)-orbits. For
