Man Cheung Tsui (FSU)
Essential Dimension
Algebra seminar
Time: 3:05pm
No location for this even specified.
Using the change of variables $x = y − a/2$, the general quadratic $x^2 + ax + b$ simplifies to the polynomial $y^2 + c$ in one parameter $c = b − a^2/2$. Similarly, a linear change of variables s... More

Man Cheung Tsui (FSU)
Differential Essential Dimension
Algebra seminar
Time: 3:05pm
No location for this even specified.
In this talk we will discuss simplifying the general matrix differential equation by means of gauge transformations. We will first review the differential Galois theory for matrix differential equatio... More

Yi Zhou (FSU)
Fast Algorithm for Desingularization of Difference Operators and Its Application in Computing $p$-Characteristic Polynomial
Algebra seminar
Time: 3:05pm
No location for this even specified.
A classical method to desingularize a difference operator is taking the left common least multiple (LCLM) with another suitably chosen operator. In this talk we present a new desingularization algorit... More

Amod Agashe (FSU)
The cohomology groups of certain quotients of products of upper half planes and upper half spaces
Algebra seminar
Time: 3:05pm
No location for this even specified.
We shall discuss the cohomology groups of quotients

of products of upper half planes and upper half spaces under the action of certain types of groups (usually arithmetic in nature). When the ... More

Amod Agashe (FSU)
The cohomology groups of certain quotients of products of upper half planes and upper half spaces II
Algebra seminar
Time: 3:05pm
No location for this even specified.
This will be part 2 of the talk with the same abstract as before (I will recall whatever is needed from the first talk): We shall discuss the cohomology groups of quotients

of products of upper... More

Abdullah Malik (FSU)
Axiomatization of Differential Cohomology
Algebra seminar
Time: 3:05pm
No location for this even specified.
Differential Cohomology is a cohomological theory which extends topological cohomology theories. These latter generalized cohomology theories are those which satisfies Eilenberg-Steenrod axioms, an ex... More
