“Fuˇcik Spectrum and Solvability of Nonlinear Differential Equations”

Bi-College Math Colloquium

Monday, April 3, 2023 - 4:00pm

Nsoki Mavinga

Swarthmore College

Location

Haverford College

Hilles 109

Tea will be served at 3:30 p.m. in the foyer outside of Hilles 109.

In this talk, we will first give an overview of the Fuˇcik spectrum of a differential operator. This spectrum corresponds to oscillations of an asymmetric system where different reaction forces act in the positive and the negative directions. A simplified model of a suspension bridge serves as an example of an application related to the Fuˇcik spectrum. Then we will discuss the solvability of nonlinear differential equations when the nonlinearity interacts with the spectrum.

Maps and Directions

We are about a 15 minute walk from the main 30th Street Station and 5 minutes from the University City Rail Station at 32nd and Spruce (=South Street & Convention Avenue). Coming from the airport by train (about 15 minutes): the University City Rail Station is the second stop after you leave the airport.

If you drive, the most convenient public parking is in the pay lot whose entrance is on 34th Street between Market and Chestnut Streets.
