Eichler shimura isomorphism

WebNov 1, 2024 · With this in mind, the Eichler–Shimura isomorphism can be obtained comparing deRham and singular cohomology, noticing that the singular cohomology of the open modular curve is given by the group cohomology . The aim of this paper is to omit this geometric interpretation and to provide a new group cohomological interpretation. WebMar 30, 2024 · By the Eichler-Shimura isomorphism, we actually give a sharp bound of the second cohomology of a hyperbolic three manifold (Bianchi manifold) with local system arising from the representation ∼k⊗∼—k of SL2 (C).

In mathematics, Eichler cohomology (also called parabolic cohomology or cuspidal cohomology) is a cohomology theory for Fuchsian groups, introduced by Eichler (1957), that is a variation of group cohomology analogous to the image of the cohomology with compact support in the ordinary cohomology group. The Eichler–Shimura isomorphism, introduced by Eichler for complex cohomology and by Shimura (1959) for real cohomology, is an isomorphism between an Eichler … WebThe Eichler-Shimura isomorphism establishes a bijection between the space of modular forms and certain cohomology groups with coe cients in a space of poly-nomials. More precisely, let k 2 be an integer and let SL 2(Z) be a congruence subgroup, then we have the following isomorphism of Hecke modules (0.1) M k( ;C) S k( ;C) ’H1( ;V(k)_); taya kyle wins shooting competition https://primalfightgear.net
