Using E-strings, we can analyze not only six-dimensional superconformal field theories but also probe vacua of non-perturabative heterotic string. We study strings made D3-branes wrapped on various two-cycles in the global F-theory setup. claim that E-strings are elementary sense combinations form M-strings as well and new kind strings, called G-strings. them, show emissions small instantons generate most known theories, their affinizations little string theories. Taking account structure compact internal geometry, special play an important role constructing D- E-types. check consistency conditions from anomaly cancellation conditions, both five-branes they given terms E-string combinations.
