Biomathematics Seminar [url]
Bursting in the Pituitary Corticotroph: The Role of Bk Ion Channels
    - Sevgi Sengul, FSU
Time: 3:35 pm Room: 107
Abstract/Desc: Pituitary corticotrophs from male rats exhibit a variety of electrical activity patterns, including spiking and several forms of bursting. Stimulation with corticotrophin releasing hormone and arginine vasopressin convert the spiking to bursting. Surprisingly, the bursting occurs even though the SK type of calcium-activated potassium ion channels are not expressed. We use mathematical modeling to understand how calcium- and voltage-dependent BK channels can produce the bursting produced by stimulated corticotrophs.

Advanced Topics Examination
MATCHING OF N-DIMENSIONAL PIECEWISE LINEAR CURVES
    - Sayani Lahiri, FSU
Time: 3:15 Room: LOV 200
Abstract/Desc: The square-root velocity framework for comparing curves will be discussed, and a precise algorithm for optimal matching of piecewise linear curves will be demonstrated, with several examples.

Topology and Geometry Seminar [url]
Expansion Complexes I
    - Dane Mayhook,
Time: 3:35 Room: 104LOV
Abstract/Desc: One can construct a planar polygonal complex from a finite subdivision rule t by means of an expansion complex. In this talk I will show that any such expansion complex K can be amalgamated in accordance with t, and that this implies an array of results, including that K is combinatorially repetitive, exhibits a combinatorial hierarchy, and that the set of all expansion complexes associated to the subdivision rule t is precisely the local isomorphism class of K.

Algebra and Its Applications
Computing the pull-back functions
    - Vijay Kunwar, FSU
Time: 3:35 PM Room: LOV 104
Abstract/Desc: Differential equations with hypergeometric solutions are very common. Let L be a second order linear differential equation with 'n' singularities. Suppose that L can be solved in terms of a hypergeometric function 2F1(a, b; c | f) for some rational function f and some fixed numbers a, b, and c. The crucial task while developing an algorithm to fi nd solutions of such L is to develop a table containing all rational functions (up to Mobius transformation) which produce 'n' singularities from 0, 1, and infi nity. Such functions are also called the pull-back functions. In this talk, I will discuss about the completeness of such table, i.e. how can we fi nd ALL such pull-back functions?
