The inviscid aggregation equation with Newtonian potential serves as a model for adhesion dynamics. In this talk, we outline a proof of short-time well-posedness of this equation in Holder spaces. This is based on joint work with Gung-Min Gie and James P. Kelliher.

In this talk, we will introduce a classical optimization problem in insurance, called optimal dividend strategies. The problem was first considered by Bruno De Finetti in 1957, and it had been intensively studied to this day. In the past, the researchers developed several types of dividend strategies which maximize the expectation of total discounted dividends. One of these, called the barrier type fascinates me. The diffusion approximation model for surplus process was proved to have the optimality of barrier strategy under some technical conditions.

We consider the symmetrized moments of three partition ranks and cranks, similar to the work of Garvan for the rank and crank of ordinary partitions. By using Bailey pairs and elementary rearrangements, we are able to find useful expressions for these moments. We then deduce inequalities between the corresponding ordinary moments. Combinatorially interpreting the inequalities gives the higher order spt functions for overpartitions, overpartitions with smallest part even, and partitions with smallest part even and no repeated odds.

Graduate Committee invites all Mathematics graduate students, faculty, and staff to participate in the Mathematics Professional Development event planned for Wednesday February 17, at 5:00-7:00pm in MLC. The event will include short presentations on professional materials required when applying for various mathematics careers (teaching in colleges, research/teaching positions, industry, labs, and other). Break-out sessions with faculty and alumni volunteers who have experience relevant to these careers and can provide constructive comments are also planned. Refreshments will be served.

The OSU Department of Mathematics will host the Annual Meeting of the Pacific Northwest Section of the MAA to be held on April 1-2, 2016. The eighth annual Northwest Undergraduate Mathematics Symposium (NUMS) will be embedded within the larger annual meeting.

The purpose of the Pacific Northwest Section is to advance collegiate-level mathematics on a regional level as well as to provide professional development and networking activities for section members and mathematics students. Much of the sectionâ€™s activities center around the annual meeting, including Project NExT (New...
