Title: De Rham isomorphism for Drinfeld modules over Tate algebras

Abstract: Two main concepts of the arithmetic on function fields are elliptic (Drinfeld) modules and L-Series. On 1970's, Drinfeld introduced elliptic modules which can be seen as an analogue of elliptic curves in function field setting and D. Goss introduced a new type of L-Series as an anologue of Rieamann Zeta Function. In 2012, Pellarin defined an L-series in Tate algebras which is a deformation of Goss's L-series. In order to give new identities for Pellarin L-Series, Angles, Pellarin and Tavares Ribeiro introduced Drinfeld modules over Tate algebras. In this talk, we talk about Drinfeld modules over Tate algebras of arbitrary rank. We also prove De Rham isomorphism for these modules under some conditions. Finally, we prove Legendre's Relation under this new setting. This is joint work with Matthew A. Papanikolas.

Groups and Dynamics Seminar

Time: 3:00PM - 4:00PM

Location: BLOC 220

Speaker: Robin Tucker-Drob, Texas A&M

Title: Invariant means and inner amenable groups II

Abstract: I will present the proof of the characterization of inner amenable linear groups which I mentioned in my last talk: A linear group G is inner amenable if and only if there is an infinite amenable normal subgroup N of G such that G/C_G(N) is amenable. The main ingredient is a "forgotten lemma" of S.G. Dani from 1985 concerning amenable actions which satisfy a certain chain condition. Time permitted, I will also discuss a closely related characterization of linear groups which are J.S.-stable.

First Year Graduate Student Seminar

Speaker: Student Panel

Title: Panel discussion: adjusting to graduate school


AMUSE

Time: 6:00PM - 12:00PM

Location: BLOC 220

Speaker: Dr. Negar Kalantar, Texas A&M University, Department of Architecture

Title: Things that Transform

Abstract: Physical transformation is all around us. However designers and engineers mainly focus on the object as an essentially static thing. How can the designer understand transformation itself as a parameter that can be shaped, and crafted? Transformation and motion have a strong bond with geometry because at its core, motion is the spatial transformation of one geometric configuration into another. In any transformation design process, there are two design efforts: the generation of an underlying geometry and the creation of an overlaid pattern. Therefore, knowing geometry is the key to transformable design. In another word, Transformation is where art, architecture, science and math merge. Dr. Kalantar with 17 years of experience in designing transformable structures will speak about her work in the field of Transformable Design ranging from a handheld toy to large structures. Also she will share: the geometric principles to create objects that change their size, shape, and surface; the principles of transformable design, such as underlying geometries and overlaid patterns; design principles of transformable polygons with scissor linkages.
