* Global stocks edge higher on prospect for solid earnings
* Euro falls sharply on persistent Greece debt concerns
* Oil slips under $86, dollar tempers high China growth (Updates with close of European markets)

NEW YORK, April 15 (Reuters) - The euro fell broadly on Thursday as worries about Greece's debt woes resurfaced while strength in the U.S. dollar kept a lid on commodity prices and global stocks edged higher on solid corporate earnings.
Late in the day Greece asked for official talks with European authorities and the International Monetary Fund, a step that could lead to the release of billions of euros from a standby aid package agreed on over this past weekend.
The yield spread of 10-year Greek government bonds against German Bunds <GR10YT=TWEB><DE10YT=TWEB> closed slightly wider at 413 basis points, but was much tighter than the session's 436 basis point high.
The euro <EUR=> was on track for its biggest one-day fall against the dollar in three weeks, down 0.78 percent at $1.3545.
"The biggest concern for the market is the Greeks don't realize how difficult it is to fund in the market and they don't have any Plan B," said Gianluca Salford, a strategist at JPMorgan. "Anything that suggests there is a Plan B is welcomed."
Further signs of economic expansion helped underpin equity markets, including an annual growth rate in China of 11.9 percent, the fastest pace of growth since 2007. But China's unexpectedly strong growth rate renewed calls for tighter policies to prevent an overheated economy and stoked speculation of when Beijing will allow the yuan to ease. [

]Mixed U.S. economic data kept Wall Street indexes little changed, though the prospects for a strong corporate earnings season have helped kindle an equity market rally that has pushed stock prices to highs last seen in the fall of 2008.
